The door has been closed for many weeks. A teenager has locked himself in - shutting out a helpless father, mother and sister. In Japan, youths like him have already been given a name: Hikikomori (the secluded). The phenomenon is also beginning to spread throughout the Western world.

All the while, the door increasingly becomes a mirror of their own lives.
