The senior partner of an investment brokerage Jeffrey has a breakdown and kills his two associates and his wife. Then he takes his three-year old daughter Victoria and the one-year old daughter Lilly and drives his car through a winding snowing road. He has a car accident and fall off a cliff, but he brings his daughters to an abandoned and isolated cabin to kill them, but the children are saved by a creepy ghostly creature. Five years later, Jeffrey's brother Lucas finds the children that were raised without social relationship and claim that they have been raised by Mama. Lucas disputes the custody with the children's grandmother but Dr. Dreyfuss, who is studying the girls, selects Lucas to take care of the children. Lucas lives with his girlfriend Annabel, who plays in a rock'n'roll band, and Victoria and Lilly moves to their house. Soon Lucas and Annabel find that the girls were not delusional and they are not alone in the house.
