A gripping episode in American pioneer history is portrayed as a determined group of settlers sets out on their 1846 journey to California, facing significant challenges. Fraught with disagreements over leadership and route, the wagon train encounters Native American attacks, scarce food and water, and harsh environmental conditions. After months of hardship, they reach the High Sierras but become trapped by an early snowstorm. Faced with starvation and the breakdown of social order, the pioneers face a deadly new danger—the erosion of trust and discipline within their own group. Directed by James L. Conway and written by S.S. Schweitzer, the film stars Robert Fuller, Andrew Prine, and Michael Callan.
