U.S. Marshal Gid McCool (George Montgomery) leads a wagon train of convicted felons to Huntsville prison in this routine western. The only female among the crooks is the dancehall girl Laura Mannon (Yvonne De Carlo), McCool's former flame. When McCool cannot be swayed from completing his lawful duty, Laura tries to endear herself to shotgun rider Mike Reno (Tab Hunter) in hopes he will set her free.
