After the programmer Zimmer dies in a car accident, he is reborn into a parallel world that looks the same but hides terror. Every night here, after people fall asleep, their consciousness will be forced into the "Nightmare Game" - a ghost world composed of countless terrifying scenes. The loser will be brain-dead in reality, and the winner will gain special abilities.
Relying on the special talent of "Death Recall", Zimmer is in danger in horror games: an abandoned hospital where the midnight bell echoes, a bloody wedding where all the guests die, a death maze that can never be exited... As the game progresses, he discovers that there is a more terrifying truth hidden behind this world, and his rebirth is no accident.
