Gianni is reunited with Paolo, the 15-year-old son he has never seen, a son he abandoned at birth. The reunion is not Gianni's idea, but that of Paolo's doctor who hopes the connection will benefit the troubled boy. Gianni experiences a Pandora's box in Paolo, full of shocks and wonders, but the key to one's house are oftern found in the keys to one's heart.
