2009 film directed by Christopher Smith

Distraught, confused, and half-wild with fear, Sarah Carter emerges alone from the Appalachian cave system where she encountered unspeakable terrors. Unable to plausibly explain to the authorities what happened - or why she's covered in her friends' blood - Sarah is forced back to the subterranean depths to help locate her five missing companions.

George Lutz, his wife Kathy, and their three children have just moved into a beautiful, and improbably cheap, Dutch colonial mansion nestled in the sleepy coastal town of Amityville, Long Island. However, their dream home is concealing a horrific past and soon each member of the Lutz family is plagued with increasingly strange and violent visions and impulses.
