Savage Land (1994)

"An epic adventure as big as the old west, as courageous as the human spirit, and as untamed as a child's imagination!"

Two women and two kids are stranded in the Old West when bad guys (posing as Indians) try to snag the stagecoach's cargo. Pitted against nature, time, and the pursuing baddies, this unlikely team must trek over the mountains to reach safety.
