A handsome stranger comes to Comanche Creek. He's quick on the draw, fast with his fists, flush with $20 gold notes-- and he soon gets himself thrown in the local jail. Everything is going according to plan Audie Murphy, World War II's most-decorated GI, portrays an Old West detective who purposely lands behind bars so he can infiltrate a secret gang with a vicious MO: spring prisoners from their cells, force them to be front men for notorious crimes, then kill them to collect the reward money for their dead-or-alive capture. De Forest Kelley, in one of his many Westerns before he became Dr. McCoy in the original Star Trek, plays an outlaw leader. He'll be dishing out lead in the gunfight finale that gives the film its title.
