Elissa (Jennifer Lawrence) and her mother (Elisabeth Shue) move to a new town only to find that they are living next door to a house where a young girl murdered her parents.

Locals claim that the girl mysteriously vanished after the incident, but as Elissa becomes close to the girls brother (Max Thieriot), she learns that a dark and terrible secret still lurks within those walls and this sinister story of murder is far from over.
