Discovering an underwater channel, they decide to swim to safety. As they enter the pool, the light from a full moon illuminates the water, creating a mysterious glow. The girls get off the island as fast as they can and back to "normal" life. One by one, however, the girls find life is never going to be normal again. They enter a wonderful, underwater world, but the nature of their powers draws them into wild adventures. And when local bad boy, Zane Bennett is rescued from a sinking boat by Emma, he turns out to be the biggest threat of all. Having seen 'something' under the water, Zane embarks on a hunt for the mysterious creature lurking out at sea. As Zane closes in, the secret of their magic powers could be revealed to the world!
