Lone and Angry Man (1965)
Shenandoah (Steffen) works his way into a band of highwaymen led by Rojo (Armando Calvo). His initiation consists of hunting down and killing a member of the gang who has 12 bullets while he is only given 2 bullets. When the bandits attempt to rob a wealthy rancher, whom Shenandoah knows, he warns him. The outlaws begin to suspect they were betrayed and commence to rough Shenandoah up. Shenandoah then reveals his true reason for joining the gang; one of them killed his wife and he is there for retribution.
