121 year old Jack Crabb (Dustin Hoffman) recounts his life in the old west. He claims to be the sole white survivor of Little Bighorn. He and his older sister Caroline are the sole survivors of Pawnee. They are taken in by the Cheyenne. Caroline escapes but Jack is adopted. He is captured by US troopers, apprentice with a snake-oil salesman, becomes a gunslinger after reuniting with Caroline, meets Wild Bill Hickok, marries and bankrupted store, follows Custer, reunite with the Cheyenne and then tricks Custer into Little Bighorn.

This is part tall-tales, part satire, part historical reimagining and more accurate than most old western. It is smart and funny. It takes sharp jabs at the old image of Indians. Dustin Hoffman is brilliant in this new world western epic. It does take random turns which is part of its charm.
