Bill Carver is a young medical-school graduate wrongly confined in prison. He escapes and finds a haven and romance in an Arizona small town. But his hopes of happiness and freedom are dashed when gangster Joe Mallon and his four henchmen show up. Mallon was the one who engineered Bill into the frame-up felony that sent him to prison along with Mallon. Bill is forced to lead Mallon and his men into an escape attempt across the blistering, sun-scorched desert.
