California, 1920. Tucker Hicks, a working cowboy and WWI Medal of Honor winner, returns home from war hoping to settle into a peaceful life with his beautiful wife Olivia. But what he finds at home is much the same as what he left; a town where Native American and Latino members of the community are looked upon as second class citizens, and subject to harsh treatment from law enforcement and government officials. When Tucker's childhood friend Carlos is arrested for a petty crime, then assaulted by his captors in unspeakable ways, Tucker's honor drives him to seek justice for his friend. Even if it means doing what he swore he would never do again after the war... kill.
