Carlos works as a superintendent of a Barcelona apartment building, a menial position that has the benefit of allowing him to admire a beautiful tenant, the ever-smiling Clara.

As the other tenants begin to realize something is amiss, the watcher becomes the watched, and Carlos finds himself in danger of being destroyed by his own perverse game.
