The film tells story about a mother, who has to confront the unbearable truth about her surviving twin son.

Rachel attends a welcome party held by the townspeople where she meets the town doctor and Helen, the latter of whom cryptically references Elliot's wish.

Elliot begins to exhibit increasingly disturbing behaviors, including him claiming that he is Nathan.

An attempt by Rachel to get the town doctor to treat Elliot ends with him insisting that she is sick and needs therapy.

Desperate for answers Rachel reaches out to Helen, who tells her that the town is part of a satanic cult.

Helen further remarks that her dead husband was possessed by an evil entity that showed up in photographs.

The following day Rachel retrieves the photographs and is terrified when Elliot doesn't show up in any of the pictures.

When she awakens Rachel is locked in her room, but manages to escape after she hears Elliot call for help.
