Seeking a fresh start, newly divorced Sarah (Elisabeth Shue) and her daughter Elissa (Jennifer Lawrence) find the house of their dreams in a small, upscale, rural town. But when startling and unexplainable events begin to happen, Sarah and Elissa learn the town is in the shadows of a chilling secret. Years earlier, in the house next door, a daughter killed her parents in their beds, and disappeared - leaving only a brother, Ryan (Max Thieriot), as the sole survivor. Against Sarah's wishes, Elissa begins a relationship with the reclusive Ryan - and the closer they get, the deeper they're all pulled into a mystery more dangerous than they ever imagined.
