American Satan (2017)

A young rock band, half of the members from England and half from the U.S., drops out of college and moves to the Sunset Strip to chase their dreams. They live in a van, and their passion and talent exceed their means to survive. An enigmatic stranger sees their true potential and emotionally manipulates them during their time of weakness. Caught in the middle of a Faustian deal, their music and controversial altercations end up influencing society beyond anything this century has seen, but can they take back control of their destiny before it's too late?
