Midnight Rose, a dancer in the Gold Coast Cabaret, loves Tim Regan, an underworld gang leader who decides to go straight in spite of entreaties from other gang members. A dying gangster requests that Tim adopt his 4-year-old son, Sonny; and realizing that the boy needs a mother, Tim induces Rose to marry him. She soon tires of housework, grows jealous of Tim's fondness for Sonny, and consequently returns to the cabaret, where Corbin, her former suitor, rehires her. When Tim, disillusioned, participates in a gang robbery, Corbin informs the police, whereupon Tim is caught and sent to prison.
