Love and success break up a vaudeville sister act.

Eddie, a smalltime vaudeville hoofer, writes a hit song and is hired by Broadway producer Zanfield to perform in one of his revues. Having long been in love with "Hank" Mahoney, the older member of a vaudeville sister act, Eddie persuades her to leave her current show and come to New York with her sister, Queenie. Eddie soon transfers his attentions to Queenie, however, and she becomes the mistress of one of Zanfield's backers in order to keep Eddie and Hank together. Hank later discovers that Eddie and her sister are in love and persuades Eddie to take Queenie away from the backer. Eddie and Queenie get together, and Hank, finding a new "sister" for her act, returns to tank-town vaudeville.
