An American black bear named Moses brings to the surface the lack of respect a father has for his son. When the father is paralyzed in a fight with Trampas, he goads the son into fighting a duel with Trampas for revenge. Trampas refuses it, but cannot ignore it.
A massive renown American black bear known as Moses once confronted Big John Beldon, but survived. Moses kills Trampas' horse at Shiloh followed by a ranch hand during roundup. Big John has the attitude that Beldons should be second to no one and tries to prove it in a fight with Trampas when Trampas dances with his son Martin's fiancee. The fight goes from fists to guns and Big John is paralyzed from the waist down as a result. He goads Martin into issuing a challenge to Trampas for revenge. In the meantime Trampas and Martin with the aid of old Faraway eventually track Moses into a cave where it takes Trampas and Martin together to kill the bear. After the roundup is completed, everyone is waiting to see Martin and Trampas settle the score.—Anonymous
