Jayne Mansfield, Marilyn Monroe's blond competition in the late '50s and early '60s, stars in this crime melodrama as Billy, the leader of a gang of thieves. She charms Jim Anthony Quayle, a widower with a young daughter, into joining the group effort on a particular robbery. After the heist, Jim personally stashes away their stolen loot while she leads the police off in another direction. But the unfortunate new recruit ends up in the clinker for five years while the others go free. Once out of jail, Jim is brought up short - Billy has allied herself with another man and her gang has money to spare - though not enough money, they decide. Against Billy's wishes, the gang takes drastic measures to get at Jim's hidden cache of loot from the robbery that sent him to jail.
