The Hunting Party (1971)

Rich, ruthless rancher Brandt Ruger keeps his beautiful young wife Melissa like a part of his property, subdued to his will. But one day she's kidnapped by the famous outlaw Frank Calder--just to teach him reading, so he tells her. Calder doesn't know or care whose wife she is. He takes care of her well, and eventually she falls in love with him. But Ruger feels humiliated. Full of hate, he sets out to kill him--and Melissa too, if necessary. Together with his friends and the newest technology in guns, which carry 800 yards, he initiates a battle on Calder and his gang.
