Two children from a working-class family in New York struggle to understand the story of God versus Lucifer as they try to deal with a mentally ill mother in this intense, realistic, spiritual drama. Angela is ten-years-old and has visions of angels. She spends much of her time trying to comprehend the tale of God and Lucifer. She also tries to protect her baby sister, six-year-old, Ellie by cautioning her to stay clean and good lest the Devil take her away. Ellie and Angela have been moved several times in their life. Their father, Andrew, is a hard worker; their mother, Mae, is becoming increasingly mentally ill. The children frequently witness her outbursts, but can do nothing to stop her sad descent. Sometimes Angela spies on them as they make love. After Mae is finally placed in an institution the girls must spend many hours on their own. At one point they assist their pregnant sitter when her water breaks. At another they manage to get away from a child molester at a carnival. In the final scene, Angela decides to baptize herself in the river and finally finds the transformation she sought.
