Molly tracks Al down in Mexico, where he is on a binge and tells him she is done taking care of him. When Molly runs into Dorothy Wayne a friend who is a dancer, she begs Dorothy to form a team with Al, because she can get Al a job if he has a partner. At first Molly is reluctant but finally agreed. 
It takes some work to convince Al, but he eventually agrees to form a team with Dorothy. They become 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 Hutchinson 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. Al flirts with Luana, Dorothy warns him about his involvement with Luana, but 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 of the murder and the necessary money is returned, with the show opening on time and to great applause. Duke tries to call off his gunmen, but 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 Al holds her, he tells Dorothy that he loves her. The doctor proclaims that Dorothy will be fine and Al's club is a huge success.
