Kit Bricca was a leader of the Bay Area protest movements of the 1960s and 70s with a fierce passion for social justice, but found the transition from activist to breadwinner a challenging one. In this moving, psychologically complex documentary, filmmaker Jacob Bricca follows the extraordinary journey of his father Kit, a man whose uncompromising idealism changed the world but tore his family apart. Kit organizes with Joan Baez and Cesar Chavez in the sixties, helps start Amnesty International USA in the seventies, then transforms himself into a high flying commodities broker in the eighties and a shamanic healer named Tatanka in the nineties. As the financial crisis of 2008 hits and Kit's finances fall into disarray, Jacob begins his search for answers by following his father on a series of quixotic adventures. Both epic and intimate, Tatanka features never before seen footage from a lost era and tells a sweeping story about the fate of American idealism, the cost of dreams, and the meaning of family.
