Plot

A new adventure of secret agent Alex Dynamo on land, in the air, and in the treacherous swamps. Alex Dynamo goes up against the S.O.S. organization, a sinister group of beautiful girls driven by a lust for blood.

MIAMI

(00:00) [As credits roll...] An coffin is taken off a jet plane by personnel of the Aerolineas Peruanas. It is transported to the International Hotel, in Miami, where four women in mourning had been waiting. The hearse is moved to a black limousine, and the women take place in a black Mercedes.

An helicopter lands, and a man in a black suit walks to a white convertible that was parked on the tarmac. The man drives with just one hand, for his left hand has a golden hand of steel. He uses a radio system in the car, identifies himself as Agent 1, and tells Solva that he has arrived. Solva gives him a rendez-vous point. Solva is one of the women in black seen earlier, and is now the current leader of the Secret Organization Service (S.O.S.), wearing a French cut swimsuit, on her yacht registered in Miami, Florida.

As the funeral convoy drives south through a highway to Miami Beach, a man is busy inside the limousine, opening the hearse's lid - revealing a bearded man with a breathing apparatus inside, very much alive. The convoy arrives at a leisure resort, where Jack has been waiting behind the wheel. The "dead man" runs to Jack's car, and takes the passenger seat. The two men aren't talking during the short voyage to Solva's yacht at the marina, where the man steps out of the car, and Jack drives away.

Solva receives Professor Yura on the deck, still in her swimsuit. The scientist has overcome some difficulties, and has completed the chemical formula, and Solva tells him that she has a fully equipped laboratory for him to work in. He needs ten days to get ready what she ordered, and Solva is satisfied with the timing, for a commando attack to destroy the oil refineries of Salinas, Ecuador.

(04:10) GUAYAQUIL, ECUADOR

Aerial shot of Guayaquil, Ecuador. A sexy blonde in a white bikini is target shooting at a mansion with swimming pool. She is contacted by radio, to go see her contact aboard another yacht. A man hands her an address: she shall take care of Dinamo, and take a man with her whom she will meet the next day at sunrise, at Punta Carnero.

As scheduled, she meets with the man, and takes the driver's seat of a red convertible. She is the S.O.S. Agent in Ecuador, and explains to him that the organization is about to recoup it's investment of five years by destroying the larger oil refineries of the country. With a loss of 30 million gallons per month, all means of transport will stop, and that will cause the collapse of the national economy. The man concludes saying that it will give the opportunity for S.O.S. to dictate the conditions not to repeat the action in other countries.

(06:20) At the cocktail lounge Huancavilca, Alex Dinamo, the International Service secret agent [Alex Cristal in the Italian dubbed version], divides his attention between Samantha the Belly Dancer, and a table where the sultry S.O.S. Agent in Ecuador and her partner are sitting.

A female photographer takes a photo of him, but she is intercepted at the bar by a lady in a red dress who bluntly takes the negative from her camera - unopposed.

Alex goes to the bar and gives a rendez-vous to the woman in red in two hours. She tells him, «Yes, love,» and warns him that the other girl is pretty and may be dangerous. Alex makes a joke at the Police Inspector that was also standing at the bar, after catching a casino chip that he tossed up in the air. It is implied that the woman in red is redheaded Maura, Alex Dinamo's assistant.

Alex pays a visit to Samantha's dressing room, and tells her that her next contact will be Barbara - but they are being listened by the S.O.S. agents in a room next to Samantha's. The female S.O.S. Agent in Ecuador decides "to take care of Barbara", and instructs her partner to dispose of Alex and Samantha.

Samantha delays Alex in her room, hugging him seductively in her white negligee. Through a moving partition on the wall, the S.O.S. henchman shoots - but Alex turns around instinctively, and it's Samantha who takes the fatal shot in the back. The gunman attempts to shoot the agent, but is killed by a shot from a special gun hidden in his left sleeve. The secret agent quickly finds the hidden microphone, and is worried that S.O.S. has heard the name of the other International Service agent.

(09:00) The S.O.S. Agent in Ecuador, wearing a dark blue figure-hugging mini-dress, drives the red car to Barbara's house, where the young woman is finishing her shower. She finds the door open, descends the stairs to the lower ground, and takes a small pistol from her garter belt. She sneaks in to surprise her.

Barbara was quick dressing up in a simple, colored frock, and happens to see the S.O.S. woman's silhouette through a curtain, and waits for her behind the bedroom door. She disarms the attacker with a kick, and they trade karate chops. Barbara goes down, showing her legs, and adroitly repelling another attack with a two-legged kick to the S.O.S. agent's chest. The S.O.S. agent was about to kick her head, but Barbara was quick in picking up the discarded gun and she shoots her in the chest, killing her.

(10:20) Aboard a submarine, the S.O.S. Commando Leader in Ecuador is showing a map to his subordinates, and giving the last instructions. It will be a quick operation, with four teams placing the explosives on the petrol deposits. All is set to "zero-six-hours".

(11:20) Barbara calls Alex Dinamo at his hotel, but the call is taken by Maura instead. Barbara gives her a rendez-vous point at "KH" - but the phone conversation has been recorded by the telephone operator, who passes the information on to the S.O.S..

Barbara enters a O.S.S. ship, and shoots dead the radio operator who had just been handed the documents with the sabotage plan. Two O.S.S. male agents heard the shot and come to see what happened, but Barbara plays a game of hide and seek, and manages to leave the ship without trouble.

(13:40) Meanwhile, Maura passes the secret code to Alex, who knows the place is in Punta Carnero.

Barbara drives a blue convertible to KH, chased by the two S.O.S. men in a car and, soon after, by S.O.S. men in a single engine airplane, from which S.O.S. fires a submachine gun on her. She stops her car on a beach, takes scuba gear from the car trunk, plunges strips to a bikini, and runs to the sea-shore. When the S.O.S. car reaches Barbara's abandoned car, she is already in the water, attired as a frog-woman.

An S.O.S. man bids assistance from a team of S.O.S. frogmen with spear-guns who operate from a yellow mini submarine. Danger for Barbara is also present in the form of a shark, a giant streak fish, and other mean looking sea fauna. Barbara manages to hide from the frogmen - stopping to breathe for a while - and to destroy the yellow submarine with a time bomb, but she is knocked unconscious herself.

Alex Dinamo watches the underwater blast from a speed boat in which he arrived just in time, piloted by Maura. Barbara tells Alex what she knows about the commando attack on the refineries, and he passes the information to headquarters, via his wrist-watch radio.

Alex swims ashore and commandeers a Chevrolet truck with dairy milk on the road, promising the driver that he will return it later.

(22:10) The nine S.O.S. commandos arrive in three rubber boats from an unseen ship, armed with submachine guns. Maura shoots at them from the speedboat, and they return fire. Maura's gun stuck, the yacht's motor stuck, and Maura becomes a good target. The Commando Leader blows up the speedboat, but Maura was already swimming ashore.

(26:20) Alex arrives with the truck on the beach, and engages the commandos in a submachine gun fight. Alex runs up a hill, and with a rocket launcher he makes a couple of killings more - four enemies down.

Barbara arrives at the shore and throws two grenades to kill two commandos that were going around the hill to surprise Alex, but she is fatally wounded by one of the men. She manages to lift herself to her knees, but falls dead on the seashore.

Maura picks a submachine gun from one of the commandos, and engages the last two in a close range gun fight, killing both - one of them being Barbara's killer. She is lightly wounded on her right upper arm. [Cut scene in the Italian version.]

Alex is wounded by the Commando Leader with a glancing shot, but then he is able to take him by surprise. They fight with knives and hand-to-hand on the rocky beach. In the end, he prevails with karate and judo. His foe picks up the discarded knife is going to throw it at Alex's chest, when the agent gets his hands on a submachine gun, and mows him down.

The Police Inspector arrives with his men, and helps the secret agents to board the police cars, as two policemen in uniform carry the body of Barbara. [Cut scene in the Italian version.]

MIAMI

(42:50) Madame Solva calls a meeting of S.O.S. agents. She is mad for having lost her commandos, and says she is sure that one of three members of the organization is a traitor. Then invites them to a drink - served by the Professor at a nearby bar. Only then does she explain that she's got a virus in a vial, able to contaminate water - and invites three agents to the adjoining bar: Agent 36, a man with blue eyes; Agent 143, a man with curly hair; Agent 380 [Agent 308 in the Italian dubbed version], a blonde in blue patterned mini dress. They drink glasses of water served by Professor Yura.

Solva explains how the virus works, and shows the effects: the piranha fishes in the aquarium where she emptied the small vial are floating dead - and Agent 36 falls dead. Solva tells the others that now that the traitor is dead, there will be no more treason ahead. She blames the traitor for the failure of the mission in Ecuador. S.O.S. may pollute the water supplies of any Latin American country, and it will become active in 48 hours - unless S.O.S. is paid for the antidote to be applied...

PUNTA CARNERO, ECUADOR

(47:40) Meanwhile, Alex Dinamo is at a spa in Punta Carnero, Ecuador, reading El Universo newspaper. He receives the visits of Maura and of the Police Inspector, but he is more interested in two sexy nurses that he hired to take care of him... a week after he'd received a clean bill of health. He also receives a letter, conveying him to depart to Puerto Rico in a haste. Maura seems to be jealous, and not trusting him that he is called to work...

Alex finds that Maura is the passenger in the seat next to his, reading the magazine Vista. She tells him that she decided to take a holiday in Puerto Rico. But he does not notice that a woman in a summer frock, sitting two rows ahead of his, is looking attentively at them both.

SAN JUAN, PUERTO RICO

(51:50) As soon as they arrive at the luggage room at San Juan's airport, a redhead girl who saw them calls the information desk, asking them to call Alex Dinamo. Alex Dinamo takes the call, and his given a rendez-vous at the Hotel San Juan.

Regina receives a call from S.O.S. Agent 64 - a beautiful young woman who had traveled with Alex in the same flight - warning Regina, the S.O.S. Agent in Puerto Rico, that Alex has received a telephone call. Regina is going to investigate the calls, but she immediately calls Jack on the radio - by the code name Black Horse - who is living in a yacht with a black cat - and sends him to terminate Alex Dinamo. He says OK, and uses a machine on the deck to sharpen the edge side of his steel hand.

By the hotel's swimming pool, a beautiful Woman in Red Bikini [played by Elsa Cárdenas], gives an order to a waiter. Jack is coming down the steps to the sunbathing area where Alex Dinamo is watching the many girls in bikinis around him. Maura taunts Alex in her patterned bikini. The waiter summoned by the woman in a red bikini brings a whiskey on the rocks to Alex - with a small disk on top. Alex takes it out of the glass, and for some reason decides not to drink.

[Sudden cut to the hotel's casino. The woman in a red bikini is not seen again - either an Intelligence Agent or yet a double agent, possibly killed by Jack in a scene cut from both the Spanish and Italian language versions.]

Solva is at the casino, wearing a red evening dress, sitting at a cards' table opposite a brunette Woman in a Yellow Dress. Solva stands, and leaves for the show room.

Alex and Maura are at the roulette table, when a buxom Woman in Decoletee Dress approaches Alex, and plays - without sitting - 100 dollars at the 00. She loses, and leaves, telling him that there is a good singer at the show room. Alex leaves after her, but Maura - who was starting to win - follows him reluctantly.

The Woman in Decoletee Dress goes to her white convertible car parked in front of the hotel, and is about to start the car when she is killed by a single chop of Jack's steel hand, who'd been hiding in the back seat.

Jack cleans the blood off the golden hand before donning a large glove over it, and joining Solva at the show room - at a table some distance from Alex's. Solva is wearing a sleeveless red evening dress, and had been at the casino watching Alex.

They're listening to the Singer - alias, S.O.S. Agent 380 - in a silver mini-dress, knee boots and... hat with ear flaps. A beautiful waitress calls Alex to the telephone, and he replies, «Thanks, beautiful!» But when he goes to the bar counter, it was only a way for the Singer to pass by him, already attired in a street suit, leaving him a message rolled in the cigarette butt she smashes on the ashtray in front of him.

Alex was wise to the Singer's maneuver, and unrolls the message: «Blue car at three». Solva hails a Rochdale taxi cab, and follows Cristal. Alex tries to discover who is the person following him, and goes outside, then he prepares a mini voice recorder with his own voice saying, «Stop! Don't move!». After a running chase down the rock bordering the beach, Alex reaches back to the machine rooms in the hotel's basement - which door was open ajar - followed by Jack. Placing the mini voice recorder away from him, and starting it by remote control, he disturbs Jack enough to knock him by surprise. Even so, Jack and Alex fight hand to hand - with Jack's steel hand breaking a water steam pipe. After knocking down Jack with an uppercut to the chin, Alex choses to leave him and recuperate his little voice recorder.

(1:05:40) Solva's chase in the taxi ends not at a dead end, but at a straight alley when another car comes between the taxi and the fugitive.

Meanwhile, Maura in a light yellow dress, red scarf around the bosom and triple pearl necklace, pays the bill and leaves the table, going to the ladies' room downstairs. She is followed by a female S.O.S. Agent 64 in a yellow mini dress and a double pearl necklace. She ambushes the attacker in the corridor, delivers a couple of karate chops dizzying her, but the girl kicks her away. Maura falls a couple of feet down the corridor, and the girl pulls a small pistol on Maura, who draws fast an evil smaller pistol disguised in her big hairdo. Maura shoots first, and the Agent 64 falls on her back, dying with a muffled scream, the hiked dress exposing her legs. Maura hurries up the stairs, and leaves, but misses Alex for a second.

Alex boarded the blue car at 3 a.m. sharp outside the hotel main entrance. Maura calls a taxi to follow him, and another chase is on.

The blue car driver is an Intelligence Agent, who takes Alex to the Singer, an undercover agent, and she tells him what she knows about the chemical attack in preparation, and the location of the laboratory. She says goodbye to him with a passionate kiss, and he leaves her at the airport. Maura pays the taxi, and goes immediately after Alex.

Appearing from nowhere, Jack shoots the Driver and the Singer with shots to the head, killing both inside the blue car, as they were still parked to watch the departure of Alex's flight. Maura loses Alex again, and is told by an airport worker that it was «the flight 421 to Miami».

MIAMI

(1:10:50) At S.O.S. headquarters, Solva tells her three senior female agents - how the virus production is progressing. Natasha, Ingrid and Monique had been present at the airport wearing black, and are now in a variety of evening gowns, like Solva is. They question the leader about details of the operation.

Aerial view of Miami, and close-up on Hotel Fontainebleau, and its swimming pool by the ocean. Solva meets again with her three of her agents, at one of the hotel rooms. From the balcony, they detect the presence of Alex Dinamo. While fondling her white poodle, she asks Monique «to take care of him». «It will be my pleasure,» the girl answers.

The svelte brunette dons a white swimming cap over her shoulder length hair, to match her white bikini, and proceeds to attract Alex's attentions. She swims across pool towards him - with close-ups of underwater photography and subjective camera from Jack's point of view, in a glass window allowing for that sort of show for customers in a basement bar. Monique feigns a French accent, asks for a hand to hoist herself from the swimming pool, throws water upon his sports suit, feigns a torn ankle. Alex starts massaging the girl's alleged sprained ankle by the swimming pool.

Maura tells him she didn't like being left alone at Puerto Rico, and the "French" Monique frees her hair to better entice the man. Maura turns her back and leaves in a rage. Monique finally asks Alex to help her walk to her hotel room

Meanwhile, Jack tells Solva that he is now going after Alex, but she changes her orders, and tells him «to take care of the girl», meaning Maura.

After going up to her room, Maura stripped down to a bikini to pick a pair of binoculars and goes to the balcony window over the pool. Jack opens the door with a master-key, but only after turning the knob - enough to call Maura's attention. She waits behind the door, and attacks him with four karate chops to the neck that floor him, but he kicks her, then he knocks her out, and takes off the glove, to use the blunt side of his steel hand to deliver a fatal blow to her head. Through the door that he had left open ajar - a blonde in a black baby-doll - S.O.S. Agent 77 - shoots him in the back, dead. Maura wakes up - fresh - and meets the blonde, who leaves, saying just that she has information for Alex Dinamo.

Meanwhile, Monique confesses the truth to Alex: she is not in pain, she just wanted his company. Before making love she wants to brush her hair, and from her hair comb she extracts a dagger with which to stab the agent in the neck. He was expecting an attack, dominates her, kisses her, and leaves her tied up and gagged in the bathroom.

On an airport tarmac, Solva and a handful of agents, including armed commandos, watch as two light airplanes leave.

Alex and S.O.S. Agent 77 are preparing to leave the hotel. Just in case, from his suitcase of equipment, he hands her a couple of smoke bombs. They almost cross Solva her senior female agents - now attired in travelling clothes - at the hotel lobby. Just then, Solva inquires about Monique. Natasha gets suspicious and follows the younger Blonde Agent... just in time to see her join Alex and S.O.S. Agent 77 leaving the hotel together in a blue Mercedes. She warns Solva via a radio hidden in their glasses: «77 has betrayed us.»

Solva takes the call at Monique's room, just as another female agent is untying her. Solva immediately understands that Agent 77 is going to lead Alex to Yuma's laboratory. She puts her commandos in alert mode, and back-slaps Monique for her failure.

Night has fallen. During the journey to the lab, Agent 77 tells Alex and Maura that she and her sister Barbara had infiltrated the S.O.S. under orders of the Intelligence Service.

The two girls jump out of the car, armed with submachine guns, and Alex drives the car into the lab compound, attracting heavy submachine gun fire from the S.O.S. commandos. With their attention concentrated on him, and on blowing up the Mercedes, the two girls shoot down a number of guards from the darkness of the wood.

Alex opens a door with a grenade, and he enters the lab, while the girls guard the door. Alex knocks out the scientist with the cross of the submachine gun, and prepares an injection of the virus that he injects on the man's neck. Without asking, Yuma opens the sealed room where the anti-virus is kept with the documents locating the contaminated waters. Alex knocks him out again, and leaves.

The last guard was hidden, and fires at him; Alex kills the guard, but is wounded in the right thigh. He passes them to the girls, then blows up the lab - with Professor Yura inside.

Solva sends a plane to pursue the three Intelligence agents across the Everglades, while Natasha and Ingrid go by jeep to the south sector, and Monique and her in two other jeeps to the north sector to cut out all escape routes. The speed run in the marshes using an air-boat ends quickly, because it had not much gasoline.

From the air, S.O.S. Pilot locates the three fugitives. Agent 77 confirms that the documents are the real thing, but Alex is not able to call Intelligence headquarters via the radio in his wristwatch. The S.O.S. Pilot throws some grenades at the fugitives who run - Alex limping - away, with returning submachine gun fire.

Solva and Monique's team happen to be in the fugitives way through the woods. Monique wounds Maura - who's wearing a black sweater and boots and a white skirt. The S.O.S. helicopter brings in a flame-thrower to burn the fugitives alive.

(1:44:35) Alex ambushes and shoots Monique, while she was hiding between two trees and brushes, and then sends a grenade to finish her. Monique dies wearing a red sweater and a white skirt. Alex uses smoke grenades to create a diversion, and approach the helicopter, as Maura and Agent 77 keep holding their weapons and the box with the anti virus and the documents.

(1:46:55) In a submachine gun duel at a short distance, Solva - wearing a white dress of military cut and a green sash hold by epaulets, and black boots - wounds the blonde Agent 77 - who's wearing the full black, figure hugging outfit of the male commandos. Alex shoots her immediately after, and Solva slumps back dead, he skirt exposing a bit of her legs.

On board of the helicopter, Alex has some trouble to start the engine, but manages to do so before the surviving commandos stop him. The International Service at last manages to contact Alex, who requires an ambulance at the airport, and complains about the shitty communication device he had been provided with. Then, he drops the wrist watch into the ocean.

The antidote and the location map are handed over to the Intelligence Agent in Miami, and S.O.S. has lost again.

Maura and former Agent 77 are recovering in hospital, while Alex is fighting against an old matron nurse who's imposing the non smoking law on him.
