With exclusive access to the lives of 8 women, ranging in age from 10 to 98, explore powerful testimonials of loss and survival and gain insight into the experience of a modern Indigenous American living on a reservation. Gripping historical accounts and startling timely statistics guide viewers down the path that has led to these present day conditions.

Award-winning documentary, Sitting Bull: A Stone in My Heart, makes extensive use of Sitting Bull’s own words, giving the viewer an intimate portrait of one of America’s legendary figures in all his complexities as a leader of the great Sioux Nation: warrior, spiritual leader and skilled diplomat. Sitting Bull’s words, as portrayed by Adam Fortunate Eagle, dominate this story. Augmented by a narrator’s historical perspective, over six-hundred historical photographs and images, and a compelling original music score, the film brings to life the little-known human side of Sitting Bull as well as the story of a great man’s struggle to maintain his people’s way of life against an ever-expanding westward movement of white settlers. It is a powerful cinematic journey into the life and spirit of a legendary figure of whom people have often heard but don’t really know.
