The unbroken cycle of sleep, eat, work is taking its toll. Then one day a young couple moves into the apartment in the building opposite. Carla's life is about to change.

Val, plagued with memories of the past, becomes convinced that a demon entity has possessed her puppets "Punch and Judy." She becomes sick, and her family thinks that she is close to death and losing her mind. Celebrating Val's birthday, the family begins to disappear, and those that remain have horrifying experiences with the puppets- and they soon learn the true story of Punch and Judy.
