A year later, Princess Atlantis and Prince William live happily on Paradise Island.

One day, William, with their ship “AGAPI”, finds a shipwreck.

With Atlantis’s  Flying Flowers’ magic and the twin dolphins, Lili & Sisi, they go to the bottom of the ocean to explore it.

But to their surprise, instead of a shipwreck they find  a sunken island, ruled by an evil wizard, Zandor.

Zandor’s wicked plan is to escape the sunken city by capturing William’s body, with hopes of destroying Paradise Island.

Lili & Sisi, who witnessed everything, warn Atlantis about Zandor’s plot.

She immediately races to action.

But, is there enough time to save William and Paradise Island?
