Stockbroker Joe Downey(Warren Douglas), mistaken in the dark for gangster "Slats" Slattery (Robert Osterloh), is brutally beaten by a rival gangster, "Knuckles" Morgan (Meyer Grace), and Downey winds up in jail on a drunk charge. His sweetheart, Marion Roberts (Jane Frazee), and friend, Bill (Harry Lauter), obtain his release, and then the three set out to find and warn the intended-victim. This pulls them into some violent incidents, including a hijacking and a murder.
