In the latter half of the 19th century, gold is discovered in the Black Hills, sacred land of the Lakota people. Gold diggers, profiteers and adventurers flock to the region. Among them is the hard-hearted land speculator Bludgeon, who tries to expel the Lakota using brutal methods. Lakota warriors retaliate, and soon the gold diggers' town becomes a battlefield.

Farsighted Falcon, chief of the Lakota, seeks refuge in the Black Hills with his wife Blue Hair and two warriors, sole survivors of their tribe. When they are attacked by the outlaw Bashan, Falcon strikes out for the town of Tanglewood to take on Bashan's boss, mining magnate Harrington.
