Blake, a dad from San Francisco, inherits his old childhood home in Oregon because his dad is assumed to be dead. Things are rocky with his wife, Charlotte, so he persuades her and their daughter, Ginger, to get away for a bit and check out the place. They arrive at the farmhouse late at night and face an unexpected attack from some mysterious animal. Forced to flee inside for safety, they lock themselves up while the creature lurks outside. As if that’s not scary enough, Blake starts acting really weird, almost like he’s becoming someone—or something—else entirely. Now Charlotte has to figure out which is scarier: whatever’s out there or what’s happening inside.
