Set in a beautiful seaside town on the Italian Riviera, an epic, romantic coming-of-age story about one young boy experiencing an unforgettable summer filled with gelato, pasta and endless scooter rides, and a young girl forced to live in fear with her older sister wanting more to explore in life. Luca shares these adventures with his newfound best friend, but all the fun is threatened by a deeply held secret: he is a sea monster from another world just below the water's surface.
