The story of Dolores Huerta — an important, yet largely unknown, activist in American history. An equal partner in co-founding the first farm workers unions with Cesar Chavez, she is one of the most defiant feminists of the twentieth century. With intimate and unprecedented access to this intensely private mother to eleven, the film reveals the raw, personal stakes involved in committing one’s life to social change. Watch the trailer.
