Cheyenne (Sean Penn of MYSTIC RIVER, MILK) is a former rock star. At 50, he still dresses 'Goth' and lives in Dublin off his royalties. The death of his father, with whom he wasn't on speaking terms, brings him back to New York. While there, he discovers his father had an obsession: to seek revenge on one of his Nazi captors who humiliated him during WWII. Searching for peace with his father's death and combating a mid-life crisis, Cheyenne decides to pick up where his father left off and starts a journey, at his own pace, across America. Also starring Frances McDormand (MOONRISE KINGDOM, ALMOST FAMOUS), Judd Hirsch (TV's DAMAGES, TOWER HEIST), and Kerry Condon (UNLEASHED, TV's LUCK).
