Set in the same universe as H20: Just Add Water (events of Mako Mermaids did not happen), 4 highschoolers are doing a Biology Project on Mako Island. Not to keen of each other but still wanting to get the work done, they discover a cave with an oh so familiar Moonpool. As magic strikes, suddenly their lives take a 180° Turn. Their normal lives as they knew them? As gone as a dead fish in a stream. Will a shared secret bring these 4 together? Or will huge waves crash between them because of it?
