In the future, humans embark on interstellar travel through leaping star gates. An interstellar spacecraft becomes unexpectedly trapped in the "Star Gate Abyss," and only 4 out of the 15 passengers have the chance to survive by entering hibernation pods. Terrified, the remaining individuals gather in the cargo hold. Faced with precious survival opportunities, someone releases a forbidden extraterrestrial monster in an attempt to manipulate it into slaughtering others. In this dark abyss, a battle for justice is unfolding.
