A spaceship is lost near the forbidden planet of Inferno II. Some years later, a second ship with a crew of nine gets there and encounters a monster that rapidly makes mince meat of most of them. The sole survivor, Makuro Kitazato, must destroy the monster before it can surprise a third ship that is already en route.
