Two women and their children arrive in Clearmont in route to California. Mrs. Chambers is looking to reunite with her husband, who has been off mining for gold, while Mrs. Larson is a recent widow whose husband died of a snake bite along the trail. The women are determined to press onward despite the onset of winter. So, Britt MacMasters, former U.S. Marshal turned rancher, and his ranch-hand Rusty, offer to escort the party through hostile territory. Also joining the party are Sheriff Wilkins, his wife Etta, and Doc Harrington. The hardy pioneers must dodge Indian attacks, stay clear of the outlaw Angel Garret and his blood thirsty band of thieves, survive rock slides, and ford raging rivers in this epic western adventure.
