The Human Jungle

While executing an armored car heist in Los Angeles, icy crook Dave Purvis shoots policeman Lt. Phillips before he and his cronies make off with the loot. Thinking he got away scot-free, Purvis collects his money-crazy mistress, Yvonne, then disposes of his partners and heads out of town. What Purvis doesn't know is that Phillips' partner, tough-as-nails Lt. Cordell, is wise to the criminal's plans and is closing in on his prey.

After two gang-related killings in "Center City," a suspect (who was framed) is arrested, released on bail...and murdered. Inspector Briggs of the FBI recruits a young agent, Gene Cordell, to go undercover in the shadowy Skid Row area (alias George Manly) as a potential victim of the same racket. Soon, Gene meets Alec Stiles, neurotic mastermind who's "building an organization along scientific lines." Stiles recruits Cordell, whose job becomes a lot more dangerous.

A police detective's violent nature keeps him from being a good cop.

An unemployed drifter, Eric Stanton wanders into a small California town and begins hanging around the local diner. While Eric falls for the lovely waitress Stella, he also begins romancing a quiet and well-to-do woman named June Mills. Since Stella isn't interested in Eric unless he has money, the lovelorn guy comes up with a scheme to win her over, and it involves June. Before long, murder works its way into this passionate love triangle.
