Alan Mitchell is a returning Korean War veteran who joins his father Walter's garment company, Roxton Fashions. The firm has been paying protection money to gangsters led by Artie Ravidge to keep the union out.
Walter's partner, Fred Kenner, sympathizes with the union's goals. After he tells Walter to sever his ties with the hoodlum enforcers, Kenner is killed when the freight elevator he enters, which was just 'fixed' by one of the hoods disguised as a repairman, plunges 12 stories to the bottom of the shaft. Tulio Renata is a union organizer trying to organize the factory, who also later gets murdered by Ravidge's men, and his wife Theresa Renata endures threats against herself and their child.
Alan Mitchell comes to sympathize with the plight of the workers. When he finally convinces his father to fire the union-busting gangsters, Walter is killed and Ravidge attempts to take over the factory. Theresa Renata takes copies of Mitchell's records to the police, who arrest Ravidge.
