Tom and Evelyn are an English couple who travel to a Spanish coastal town to finally enjoy a belated honeymoon. However, upon arrival, they are disappointed: the place is too bustling for the peaceful holiday they had planned. They decide to rent a boat to visit a small island where Tom had been when he was younger. Their surprise is immense when they discover that the island's only inhabitants are children, children who, driven by a mysterious force, rebel against the adults.
