The Setup: OK, so, Alex is dead. But, hey, at least Rocky makes it outside! She runs for it, but not without the blind man unleashing his blood-thirsty dog. Rocky ends up making it to her getaway car, barely, and concocts a quick plan that leaves the dog trapped in the car.
The Fifth Twist: Well, even after her long, heart-stopping tangle with the dog, the blind man has managed to find her after all. He knocks her out and drags her back to his home.
