The movie is about a 10-year-old girl named Angela (Miranda Stuart Rhyne) who comes from a dysfunctional family; her mother Mae (Anna Thomson) suffers from mental illness with frequent mood swings and her father Andrew (John Ventimiglia) is trying his best to keep the family together. Believing that the reason of Mae's mental illness is because of her sins & having visions of Lucifer coming to take her and her little sister Ellie (Charlotte Eve Blythe) away, Angela creates religious rituals and stories to purify herself and Ellie so her mother will get better.
