An irresponsible Broadway star gets mixed up with gambling and gangsters.

Broadway star Al Howard has a habit of walking out on hit shows. Although Molly, his sister, promises his agent he will never do it again, he is banned from Broadway. Molly tracks Al down in Mexico, where he is on a "binge," and tells him she is through taking care of him. When Molly runs into Dorothy Wayne, a dancer friend, however, she begs Dorothy to form a team with Al because she can get him a job if he has a partner. At first Molly is reluctant, but finally she agrees. It takes some work to convince Al, but he too agrees, and they are a big success in Chicago. Dorothy falls in love with Al and, thinking that he does not return her affection, decides to quit the act. Al asks her to stay, telling her that he plans to open his own nightclub on Broadway. Molly introduces Al to Duke, a gangster who is willing to back the club as a showcase for his wife, Luana Bell, a torch singer who wants to make a comeback. Although Dorothy warns Al about his involvement with Luana, Al continues his flirtation with her. Duke gives Al an additional $30,000 to open the club, but before opening night, Al uses the money to post bond for Molly, who has been arrested on suspicion of murder. When Al turns down a proposal from Luana, she angrily tells Duke the club will not open on schedule, and he sends gunmen to kill Al. At the last minute, Molly is cleared, the necessary money is returned, and the show opens to great applause. Duke tries to call off his gunmen, but jealous Luana does not give them the message. Al finally realizes that he is in love with Dorothy and asks her to dinner. As they step out the door, Dorothy sees the gunmen and throws her body in front of Al. She is wounded and as he holds her, Al tells her that he loves her. The doctor proclaims that she will be fine and Al's club is a huge success.
