Molly and Michael, like most kids, weren't thrilled when their mom remarried, especially due to their creepy new stepsister, Heather, who seems determined to blame small problems on them and start fights. Exacerbating the problem is the new family's move to an old house (a converted church) in the country. There, Heather's eccentricities grow worse. Molly and Michael's possessions are destroyed and Heather begins talking to an invisible friend named "Helen." After Michael and Molly do some research, they realize that this is no ordinary invisible friend--Helen is the ghost of a long-dead girl who once lived in the house. And she seems to want Heather to be her friend, forever and ever. Unfortunately, Molly's mom and Heather's dad don't believe the ghost bit. Molly and Michael must put aside their feelings about Heather in order to do what they know is right: save her from evil.
