The Columbia programmer Sinner's Parade stars studio utility player Victor Varconi as shady dance-hall proprietor Al Morton. Schoolteacher Mary Tracy (Dorothy Revier) goes to work for Al to support her family. When Bill Adams (John Patrick), the son of anti-vice campaigner Mrs. Adams (Clara Selwynne), falls for Mary, she tries to quit her job, but Al won't let her. The girl's resentment for Al intensifies when the joint is raided and she loses her teaching job as a result. Amazingly, however, Al turns out to be the hero of the piece when the "respectable" Bill Adams reveals himself to be a gangster boss, whereupon Mary saves Al from being taken for a ride by Adams' hired goons.
