Davide is a frustrated teacher who lives with his wife and son in a quiet apartment building in the suburbs. He is a creature of habits with an uneventful life. His daily routine is disrupted when one of his neighbors welcomes a homeless man in the building’s courtyard. All of the residents start caring for him, as he seems to fill their lives with pure joy, yet without ever uttering a single word. Davide, too caught up in his own miserable life to welcome such a change, starts harboring a deep hatred for the man and tries to get rid of him, with scarce results. Eventually, as his wish comes true, the disappearance of the man will have unexpected effects.
