When Arapaho Ned Windsong is shot to death, his alleged fiancée Marcy, an outsider to the tribe, is the only witness. Even though she identifies two Arapaho troublemakers, Ned's family clings to the belief that Marcy herself was responsible. Convinced of Marcy's innocence, Vicky Holden represents her, finding herself at odds with her people and her friend Father John O'Malley. When the accused men are found murdered, new suspects surface, and Father John and Vicky find themselves in a web of lies and deceit, up against a master.
