Lugano, Switzerland. Titta Di Girolamo is a discreet and sullen man who has been living for almost a decade in a modest hotel room, a prisoner of an atrocious routine, apparently without purpose. His past is a mystery, nobody knows what he does for a living, he answers indiscreet questions evasively. What secrets does this enigmatic man hide?
