In the Mohave Desert, Olga runs a gas station, lunch counter, and auto camp with her younger sister Myra. In a 24-hour period, Olga must deal with Myra's desire to go to a town dance with a cad, the appearance by happenstance of George, an old boyfriend whose conduct is never above suspicion, and the overnight presence of two women recently divorced in Reno, who, with a chauffeur, are carrying valuable jewels. George gets wind of the jewels and plays with Olga's heartstrings to set up a robbery. Myra arranges to sneak off with her beau. It's hot, and the heat lightening is crackling on the horizon. Is Olga's life of peace and hard work in the desert about to change for the worse?

A cowboy competes with a gambling tycoon on the Barbary Coast for the hand of a beautiful dance-hall queen.
