Jimmy O’Connor and Scotty are a couple of New York City gamblers and sharpies who decide to go straight and, since they are such good friends, split 50-50 “even steven” on anything they get or do. Jimmy, a confirmed bachelor, doesn’t care for women but Scotty falls in love with Diana O’Sullivan, a Coney Island girl. They decide that Jimmy needs a girlfriend and they opt for Jeannie Cavanaugh. But, following their 50-50 pact, Jimmy, although he has fallen in love with Jeannie, praises Scotty to her. It takes an airplane ride to get everybody matched up correctly.
