Fury at Showdown (1957)

Reformed ex-convict Brock Mitchell (John Derek) completes a prison sentence for shooting a man in a desperate act of self-defense and travels to the ranch run by his brother, Tracy (Nick Adams). Now an outcast in his own hometown, Brock throws himself into raising animals and working the land. As the newly reconciled Mitchells make up for lost time, vicious gunslinger Miley Sutton (John Smith) finds himself on the payroll of the crooked brother of the man Brock killed.
