Set in the land of dreams, "American Satan" tells the story of a young rock band, half from England and half from the US, who move to the Sunset Strip to chase their music dreams. Living in a van, their passion and talent exceed their means to survive when an enigmatic stranger (Malcolm McDowell) preys on the emotional turmoil lead singer Johnny Faust (Andy Biersack) finds himself after learning of his mother's (Denise Richards) illness.

Manipulating this time of weakness for the band, he offers them a deal that will set them on a path of fame, fortune, and ultimately dark destruction. Caught in the middle of a pact with the devil himself, their music and controversial altercations end up influencing society beyond anything this century has seen.
