The Mountain Men (1980)

In the twilight of the fur-trapping era, hardened mountain men Bill Tyler and Henry Frapp encounter Running Moon, a woman fleeing a brutal marriage. Seeking refuge from her abusive husband, Heavy Eagle, she finds unexpected shelter with the two rugged trappers. Unbeknownst to them, their act of compassion ignites a powder keg. Heavy Eagle, consumed by rage, unleashes a relentless pursuit, dispatching a formidable war party to reclaim what he considers his own. This sets in motion a collision course of cultures and survival.
