Elizabeth Olsen (Martha Marcy May Marlene) stars in this suspenseful, edge-of-your-seat thriller presented in real time as one shocking, uninterrupted shot. When Sarah (Olsen) finds herself sealed inside her family's secluded lake house with no contact to the outside world, panic soon turns to terror as events become increasingly ominous. Directed by filmmaking duo Chris Kentis and Laura Lau (Open Water), it's a tension-filled journey that Scott Mantz of Access Hollywood raves is "Beyond terrifying! Clever, gripping, intense and scary as hell"!
