An interstellar spaceship was accidentally trapped in the "Star Gate Abyss". Only 4 of the 15 passengers were able to enter the hibernation cabin and get a chance to survive. Faced with precious survival opportunities, some people released the imprisoned alien monsters and attempted to manipulate them to kill others; others fought desperately against the monsters, even sacrificing their own lives to save more people. In this dark abyss, a battle for justice is beginning.
