Something is very wrong with the creatures of the deep. Their bodies encrusted with strange barnacles, the shells opening and closing like clicking, winking eyes. Black tentacles flail out of them, scooping the meat from their prey. The host, be it a whale or a shark or a dolphin or a tuna…or a human, become mad once infested, the only thing on their mind… tearing any living thing apart, feed the parasite. Stuck in the middle of a sea of nightmares, surrounded by massive, murderous beasts, with their insane uncle just as much of a threat, two brothers and their friends fight to survive before the hungry sea tears them apart.
