How far would you go to find your father missing and presumed dead five years ago, but who had just communicated with you in a totally unpredictable way? Frank Payne, a 17-year-old boy, has just received an enigmatic stone from the sea that turns his life upside down, after discovering some inscriptions in an unknown language indicating the whereabouts of his father. With his friend Barbara and his grandfather Walter, they leave for the Mariana Islands, in the extreme Pacific, where they find a submarine that takes them to the depths of the ocean, precisely in the Mariana Trench. In addition to being an inhospitable place inhabited by strange creatures, the region still hides a secret passage to a somewhat mysterious cave. It is like this, between enigmas and sinister adventures that know the true power of the legendary water stone and the intentions of a fearsome villain, who will do everything to find the other piece of this relic that is with Frank and join it to the other three (fire, air and earth) to put his evil plan into action, to destroy the planet. Grab your backpack, your passport and embark on this electrifying and fantastic adventure and discover the humanity's greatest secrets.
