Joe Grange quits his job as a Los Angeles accountant and gambles all of his savings on a racehorse named Gallant Man, the longest of longshots. He has his cab driver friend Toby Gleeton bet for him. Meaning well, Gleeton bets everything on the favorite, but Gallant Man wins.

Toby has helped introduce Joe to the love of his life, Ronnie Moore, who puts up with Joe's gambling for a while. But when she expects a child, even Joe's winning of a house does not make her trust his ways. Joe is too busy playing poker to be there when son Richard is born, and he is suckered by horse trainer John Ramsey into betting $40,000 on a race, blowing it all.

Having lost his wife and money, Joe is desperate to put things right. When he hears Ronnie is entering Gallant Man in a $100,000 race at Hollywood Park, he tries to stop her before she loses everything. It turns out she knew exactly what she was doing, and even forgives Joe after their horse's victory.
