Academy Award winner Clark Gable stars with Alexis Smith as a gambler with a heart of gold who runs the rarest of all things, an honest casino, where Any Number Can Play. Despite Charley Kyng's (Gable) honor, his wife, Lon (Smith), and son, Paul (Darryl Hickman), view his business with disdain. But on the day that Paul is arrested for a brawl and Charley is diagnosed with a dangerous heart condition that will require him to stop gambling, Charley brings his wife and son to the casino for his last night of gambling. As they watch, Charley loses and wins back a fortune, thwarts a robbery, and bets the casino itself on a single turn of the cards.
