The sea is deep and full of secrets. More people have walked on the moon than have been to the very bottom of the ocean, but that's where our heroes, the Nekton family, dare to go. While most of us look up to the night sky, the Nektons know that infinite mysteries lie deep in the darkness below. For generations, members of this family have been explorers of the deep. A brilliant team with advanced technology and an unquenchable thirst for discovery, they boldly explore this spectacular world of mystery where they must face astonishing creatures, dangerous pirates and mysterious Guardians!
