Antonio

トトイ

A young boy, accompanied by his father and younger sister, returns to the sun-drenched Mediterranean island of Sardinia after his mother's death. Residing with his aunt and uncle, Antonio—who is called Tottoi by his cousin—assists in restoring the old family house and takes pleasure in swimming in the sea.
Inside the ancient sea caves, Tottoi finds an adult seal and her pup, a species long believed to be extinct on the island. He plans to keep this discovery hidden, but news spreads quickly, and it is not long before sinister men become interested in profiting from Tottoi's find.
