A gang of outlaws is murdering miners and taking over their claims, but they cross the wrong man when they target the father of Luke Cromwell (Audie Murphy), a gunslinger known as the Silver Kid. The local marshal, Lightning Tyrone (Stephen McNally), is also tracking the gang, but receives a crippling injury during a gunfight. Tyrone deputizes Cromwell, and the two take on the murderers together, while trying to resist the charms of Opal (Faith Domergue), the new beauty in town.
