Taking place on the Navajo Nation, Cloyd Begay (Beau Benally), has been a victim of alcohol abuse and domestic violence throughout his childhood as a result of his resorting to alcohol to repress his memories. As he is willing to take responsibility for his life as a husband and father, Cloyd's drinking buddies Jimmy (Gerald Vandever) and Marty (James Junes) cultivate his continued participation in their carefree lifestyle of drinking and partying, thus preventing him from making significant changes. All the while, his wife Lorraine (Kim White) and son Michael (KJ White) begin to lose hope in him and seriously consider leaving him. As the ensuing events unfold, it leads him to make a life-changing choice.
