Plot

Two feuding bounty-hunter families have to team up to track down a criminal couple.

The film opens with two bounty-hunters called the Flying Daggers Hon-Chung and his nephew Hon-Lam attacking and killing a group of bandits known as the Thirteen Cold-Blooded Eagles. After having slain them all, they are soundly thrashed by the Sisters of Bewitchment Lady Fung and Fung-Ling, two bounty-hunter sisters, who steal the bodies and claim the credit and bounty for having defeated the Eagles. The Hons shrug this off, because both parties are attracted to each other (Hon-Chung even wooed Lady Fung once), and because they have bigger business at hand...

The Hons are summoned to the palace of Emperor Tsao, who orders them to track the notorious thief Nine-Tails Fox and his wife Flying Cat, who broke into Tsao's home, raped and killed his daughter, and stole everything. He offers a reward of one million gold coins to capture Fox and get back his property, to which the Hons accept.

During their travels, they overhear that the Death Gods, a fearsome quartet of warriors, have captured the Fung sisters. Despite wanting to get on with their own business, they decide to go and rescue them. They kill three of the Death Gods... then discover they in fact hired a group of prostitutes for pleasure. It was a setup by the Fungs, who want to capture Nine-Tails Fox and get the reward for themselves. They leave the Daggers at the mercy of the last Death God Never-Die, a warrior said to be immortal; he makes good this claim by getting his head and hand severed and still continuing the fight. The Hons make a run for it, but Never-Die's hand acquires sentience and becomes fond of Hong-Chung, refusing to let go of him; Never-Die (getting his head back) chases them, demanding that they return his disembodied appendage.

At the hideout of Nine-Tails Fox, Fox and Cat each display goods they stole; a quarrel and fight develops between them over whose goods are better, and Cat storms off. The Fungs arrive and attack Fox, but he is able to defeat them both; then the brothers arrive with Never-Die in pursuit, and an utter free-for-all takes place. Never-Die captures Hon-Lam and Fung Ling in a vicegrip and starts to crush them; facing their end, the two profess their long-kept affection for each other... which causes Never-Die to spasm. Fox surmises that mushy sentimental talk is Never-Die's weakness, and Hon-Chung and Lady Fung start acting intimate and groping each other (with Fox joining as a threesome), causing Never-Die to dissolve into a puddle. With this crisis over, the Daggers and Fungs go back to business and take Fox captive, deciding to share the reward. Later Cat comes back and sees evidence that Fox had two women AND a man over, to her disgust and confusion...

During the trip back, Fox is able to get loose, and heads over to a brothel for pleasure, but he is tracked by Never-Die's hand (now formally adopted as Hon-Lams pet) and soon the Hons and Fungs catch and bind him again. The party later stops at an inn hosted by Innkeeper Pang and his wife, who entertain not only a troop of Japanese warriors, but a bevy of travelling women... led by Flying Cat. The Japanese warriors attack the party to catch Fox, and in the chaos Cat's women escape with Fox, but soon the warriors are defeated and Fox is recaptured (along with his wife Cat, whom Hon-Lam douses in water to render her ineffective). Meanwhile, Emperor Tsao employs two transgender warriors, the Erotomania Man and the Yi-Ho lady, to take out Fox and his bounty hunters...

Fox and Cat admit robbing Tsao, but they strongly deny hurting or killing anyone. While the hunters are pondering on this, the inn is attacked by the transgender warriors. The Hons and Lams fight them off, but the Yi-Ho strikes Hon-Chung with a lethal poison kiss. Pang explains that the cure for this poison is to have a lady make love to the victim nine times, then when three days later the consequent offspring is born the patient should cook and eat it. Thus Hon-Chung carries Lady Fung to a bedroom; a grining Pang says there was another cure but decided not to mention it, but then gets a dose of the poison from his wife, whom he has kept out of his bed their whole marriage. Meanwhile Hon-Lam and Fung-Ling try to court each other, but are suddenly captured by Tsao.

The next morning, a rejuvenated Hon-Chung discovers that Fox and Cat are free. They show him a hidden letter they found when they searched the goods stolen from Tsao, which identifies Tsao as a spy working for a foreign power. He then gets word from Tsao that when Fox and Cat are surrendered to Tsao, then Hon-lam and Fung Ling will be set free. The handover goes ahead, but Fox and Cat break free and an epic final fight commences, during which Hon-lam is able to break free of his bonds. Fox and Cat scratch the transgender warriors to pieces, but soon they are all overwhelmed by Tsao's gale-breath attack. Never-Die's hand manages to stop up Tsao's mouth and nose, giving Hon-Lam the opportunity to blast him to smithereens.

The film ends with everyone eagerly awaiting the birth of Lady Fung and Hon-Chung's child, as since Hon-Chung was cured beforehand there's no need to cook the child... only to see to their horror that Never-Die has returned in the baby's body!
