Misty awakes with a cold in a bed unfamiliar to her. At the foot of the bed, the owner of the place, Ashton, obsessively attends to her. He claims to have saved Misty from an accident in which she drove her car into a lake. Misty has no memory of this event and questions why she would act in such a way in the first place. Instead of easing her worries, Ashton leaves Misty alone so she can rest, but promises to check back in later. While trapped alone in the room, increasingly strange occurrences happen to Misty, and glimpses of the accident begin to surface. What truly happened at the lake? Who is Ashton, and does he know more than he lets on?
