When Allyson Simon separates from her husband Jonathan and moves with their 9 year old daughter Claire to a big old house in the country, she learns that their realtor never told her about the fact that a brutal family murder happened there five years ago. As Allyson, and later Jonathan, discover to their horror, an evil South American doll has been left behind--the same doll that belonged to the 10 year old who killed his family--which eventually possesses Claire, turning her into a terrifying, murderous entity that neither Allyson or Jonathan can recognize as their little girl.
