Cora and the Coral Reefs

The adventures of an 8-year-old indigenous girl, Cora, and her 9-year-old cousin, Cauê, on a trip on their grandparents' boat during Carnival. After losing a plastic bag at sea, Cora discovers that coral reefs are not rocks scattered across the sea, but rather colonies of living beings that are essential for the balance between the web of life that exists between the sea and the land.
