It's hard to be a producer when you're a koala and have paws. It's even harder when your faithful assistant is older than a typewriter. And it's fun when your cast is a nonstop dancing chubby boy, a prickly punk girl, a shy schoolgirl, a big-ass gangster, and a mother of many children whose kids are piglets in the literal sense of the word. The recipe for success is simple: rush to the entertainment capital of the world, recruit a legendary rock musician, and blow up the stage with a new show.
Luca, a cute little boy, is having an unforgettable summer on the Italian Riviera, full of gelato, pasta and countless scooter rides. Luca shares these adventures with his new best friend, but all the fun is threatened by a deeply hidden secret: he is a sea monster from another world, located just below the surface of the ocean.
