The biggest small movie of the year cost just $15k to make, but every dollar went in to frightening you to death.  Listen back to our lowdown on the documentary-horror hit.

After a young, middle class couple moves into a suburban 'starter' tract house, they become increasingly disturbed by a presence that may or may not be somehow demonic but is certainly most active in the middle of the night. Especially when they sleep. Or try to.

Things go horribly wrong as they record the increasingly violent and intrusive night hauntings, as it quickly switches from a curious study in to a fight for their lives.
