Virginia congressman Gene York (Michael Woods) and his attorney wife Karen (Faye Grant), after numerous failed attempts to have children, go to a nun-owned orphanage where they adopt a child that they name Delia from a nun named Sister Yvonne (Megan Leitch). At first, other than Delia scratching Karen and the later heart attack of the preacher overseeing her baptism, all seems normal. But seven years later, after the Yorks adopt a rottweiler that they name Ryder, Delia (Asia Vieira) starts to display the traits and personality of an increasingly violent and manipulative sociopath. Furthermore, as the family doctor, Dr. Hastings (Madison Mason) reveals that she is going through puberty, strange events begin to occur around Delia, including the death of the father of a boy whom she terrorized. Jo Thueson (Ann Hearn), a New Age practitioner hired by the Yorks as a nanny to help while Gene runs for the Senate, senses something suspicious about Delia after finding her healing crystals blackened by the girl's touch.
