In 1825, English peer Lord John Morgan is cast adrift in the American West. Captured by Sioux Indians, Morgan is at first targeted for quick extinction, but the tribesmen sense that he is worthy of survival. He eventually passes the many necessary tests that will permit him to become a member of the tribe.
In the early 1800s, a group of fur trappers and Indian traders are returning with their goods to civilization and are making a desperate attempt to beat the oncoming winter. When guide Zachary Bass is injured in a bear attack, they decide he's a goner and leave him behind to die. When he recovers instead, he swears revenge on them and tracks them and their paranoiac expedition leader down.
Lord John Morgan has returned to civilized life in England, but finds he has nothing but disdain for that life. Yearning to embrace the simplicity of the American West-and the Yellow Hands Sioux tribe he left behind, Morgan returns to the tribe's land only to discover that they've been decimated by ruthless, government-backed fur traders. Led by Horse, they fight to repossess their land.
