The Deep follows the adventures of the Nekton family--a brilliant team of underwater explorers. With state-of-the-art technology and an unquenchable thirst for discovery, the Nektons explore the mysterious depths of the ocean, where most of our world lies unexplored and unexplained.

While others look up to the stars, this family knows that an infinite number of things shine brightly in the darkness below. In the deep they hunt for the colossal squid, encounter an ancient wooden submarine and race prates to a lost treasure.
