A Los Angeles criminal plots the robbery of a ship carrying $2 million worth of surplus narcotics left over from World War II. His plan goes awry when his backer's girlfriend, drafted into a key role in the plan to keep an eye on the bigwig's up-front investment, falls for an ambulance attendant who is an unsuspecting pawn in the scheme.
The climax was filmed at Terminal Island, where hundreds of obsolete "Red Car" inter-urban electric trolleys were stacked awaiting scrapping.
