But this year, something is amiss—starfish have mysteriously disappeared from the beach, and the ocean seems to be losing its vitality. Alongside her new friend, Ben, Ellie embarks on an adventure to uncover the truth behind the strange happenings.

As the two friends dig deeper, they discover an ancient legend about "The Keeper of the Light," a mythical protector who once safeguarded the island's delicate balance between land and sea. Their investigation leads them to hidden secrets beneath the island’s lighthouse and an ancient treasure that holds the key to restoring the island’s health.

However, they soon realize that an evil group of businessmen is trying to exploit the island’s resources, threatening everything Ellie and Ben hold dear. With the fate of the island hanging in the balance, Ellie and Ben must summon all their courage and wit to defeat the villains and protect the ocean.
