Porpoises as large as locomotives leaping in a monstrously incredible sea! Sharks larger than subway cars! Mammoth creatures that hunt their prey in waves larger than mountains! Huge killer ships patrolling the skies!

Captain Steve Burton and his band of marooned earthlings are trapped in a terror-blasted sea boiling with bizarre peril. Desperately the space wanderers dive deep into the center of the ominous ocean in a frantic attempt to find freedom... or die!
