Five people start their journey from Independence to the promised land of California in 1848. They travel through prairies, rivers, mountains, and desert and encounter others on the trail and face many dangers.

"The year was 1848 and the great California emigration was still twelve months distant. The flakes of gold had already been found in the race of Sutter's mill, and the thin scattering of men, which made the population of California, had left their plows in the furrow and their ships in the cove and gone to the yellow rivers that drain the Sierra's mighty flanks. But the rest of the world knew nothing of this yet. They were not to hear till November when a ship brought the news to New York, and from city and town, from village and cottage, a march of men would turn their faces to the setting sun and start for the land of gold."
