Cade has been a Leviathan for as long as he could remember, which unfortunately doesn't go further than 3 years since he's been imprisoned in a facility at the bottom of the ocean floor by the Pacific. With no memories of his past, except for flashes, he has no idea what's beyond these walls and above the surface. He only knows of the war that's supposedly been going on for a while now, a war of superpowers in which others like him are used as soldiers to fight after undergoing countless torturous experimentations. He has no idea who he is or anything about his past or even why the woman in charge want him so badly. Soon he and others like him embark on a journey against the very people that took their lives away. Can he and his friends beat them or will they fall as victims of the supreme might of Arachne?
