The young boy Luka, around whom the whole storyline of this artistic picture will revolve, will tell about his carefree childhood. The viewer will be shown all the charms of that wonderful time that schoolchildren look forward to every year, namely their long-awaited holidays.

Luca will spend this happy time in one of the seaside towns, which is located on one of the Italian Riviera. This boy simply could not be without adventures, so for maximum fun, Luke needed to find a best friend, which he eventually did. But here, behind the mask of an ordinary guy, a real monster was hiding, because it was just a kind of shell, inside of which there was a real underwater monster.
