This is a low budget programmer that tries to imitate the popular G-Man films of the period. In the late 1940's and early 50's, there was a string of G-Men type films with titles like, C-MAN, T-MEN, FEDERAL AGENT at LARGE, REVENUE AGENT and so on. Some of these were cracker-jack bits of entertainment. This is not one of them.
This low renter is about a group of Federal Narcotics Bureau types on the trail of a crew of drug smugglers. The Feds have a bee in their bonnet, after one of their number, is shot up in a drive by. The Federal bunch, are led by agents, William Henry, Robert Shayne and Lyle Talbot. The villains of the piece are controlled by George Eldredge. His gang includes, Noel Cravat, Dennis Moore, Paul Hoffman and Joe Turkel.
The Government types know that the smugglers are bringing the heroin over the border from Mexico. They are just not sure how. They enlist the help of Mexican cop, John Laurenz. Also in the mix on the Mexico side, is the ex-girlfriend, Movita Castaneda, of a now dead member of the criminal gang. She is used to help point out any other gang members that night show in Mexico.
After a few days the Feds get a break, a couple of the smugglers are pointed out by Miss Castaneda. The criminals have a nifty way of smuggling the drugs back to the U.S. The smugglers clamp a small box containing the drugs underneath an American tourist's car. They take the plate number down. They then follow the tourist back to the States. Once over the border, the crooks retrieve said cargo when the car parks on the American side, nice and simple.
Now the Federals need to discover who the boss of the operation is. They question a woman, Lori Irving, who had witnessed a killing by the gang. Irving is an elevator operator in the office building suspected of being the headquarters of the drug mob. (Which it is) Needless to say Irving is soon rendered speechless after a great big honking sedan runs her down.
The Feds now put one of their own, Pamela Blake, into the now vacant job. The Feds wire up the elevator with a camera and sound. They hope to see someone they might know from the mug books etc. This happens, and gang member Joe Turkel is grabbed up for a bit of friendly third degree. Turkel holds his tongue and is soon released. The Feds however trail the man as he leads them to the boss, John Eldredge. The Feds now wire up Eldredge's office for a bit of evidence gathering.
Things go sideways when the mob tumbles to the Federal operation. They grab up an agent to use as a hostage. There is a large shootout as the villains attempt a getaway. Lead flies and the crooks come out on the short end of the exchange. Eldredge is ran over and killed by his own men during the gun battle.
Though made on an obvious shoe-string budget, it only runs 67 minutes, and does supply a few thrills. Not a world beater, but, if you are a fan of low rent programmer fare, it will pass the time well enough.
