A white humpback gets trapped in a lagoon at Long Island. This unusual event stirs up the otherwise quiet life on the Bahamian island. Luckily, Marijn and Talitha succeed in rescuing the animal in the nick of time. At that moment they discover why the whale came to seek them in the first place. It's the beginning of a thrilling journey, aboard the Moby Dick, a ship built solely to attack and sink illegal whale hunters, taking them from the sunny Bahamas all the way to the deep southern waters, looking for the lost continent of Atlantis.
