Gunsmoke (1955)

S07E23 Reprisal

Oren, a rancher with a penchant for drinking, gambling, and chasing women, had a devoted wife waiting for him at home. When Matt is pushed to the point of taking Oren's life, he must deliver the heartbreaking news to her. Instead of mourning, she becomes consumed by a desire for vengeance, and her sights are set squarely on Matt as the one responsible for her husband's death.
