Teenagers from various suburbs of Rome (Ostia, Pomezia, Tor Bella Monaca, Fregene, Testaccio, Nomentano, Pigneto, Aurelio) take part into a musical contest "CAPUT MUSICAE" organized by a prestigious Classical Lyceum in the center of the Caput Mundi: music is what connects two different - but not so different - worlds, inspired by Catullo's classical theme "Odi et Amo" (also the theme chosen both by Marco and Federica for their songs, maybe not by chance.. ). Making a new statement: "Omnia Vincit Musica".
