With Sitting Bull at the Spirit Lake Massacre: The story of a controversial white settlement in 1860s Spirit Lake, Iowa. Unbowed by the encroachment, Chief Sitting Bull vows to reclaim the land of his fathers. A long-thought-lost film finally surfaces after being unseen for over eight decades. Created and copyrighted by Sunset Productions in 1925 but not released until June 15, 1927, this silent epic features the superior Native American actor Chief Yowlachie (performing here under the name Chief Yowlache) as Sitting Bull.
