Biff Jones (Jack Carson) – the favourite ice cream salesman (known as a “Good Humor man” in the States) of the kids – becomes involved in a struggle with three gangsters over a blonde. The thugs win and stuff Biff into his own freezer. The police rescue Biff, but he is fired.
The blonde – a gangster’s moll called Bonnie (Jean Wallace) – turns up again and Biff conceals her in his flat, but later he cannot distinguish her from a corpse. He immediately informs the police, but by the time they arrive the “body” has disappeared.
Biff is then implicated in a hold-up but his pretty girlfriend Margie (Lola Albright) comes to his aid, along with her kid brother, Johnny (Peter Miles). So do all the youngsters of the neighbourhood.
In the end, Biff is able to solve the mystery of the blonde and prove that Margie’s boss, insurance investigator Stuart Nagel (future Superman star George Reeves) is the man behind the trouble.
