Mark Harris looked like a man... But seven miles below the surface--without diving gear or breathing apparatus--he moved along the ocean floor like the sea-being he was. Before him a door opened in the side of an underwater mountain to reveal a sinister threat to the terrestrial world.
A power-hungry genius had lured the best scientific minds in the world to his secret laboratory in the impenetrable depths of the sea. There he had created a computerized war machine which would wipe out life on earth and establish him king of an underwater empire.
Only Mark Harris could penetrate his infernal habitat to save life on earth. . .the earth where men breathed air...the earth which was not his home.
