After spending the night together, Clare wakes up alone in Andi’s apartment to discover the door locked and the windows secured, with no means of escape. Now the only inhabitant of an otherwise abandoned apartment complex, Clare must confront her lover to have any hope of escaping the nightmare of her confinement.
