To pay for his sister's treatment, Erik Segrave enters the deadly holographic game "Abyss Corridor", where clearing it grants a five-million-dollar prize, but failure means obliteration. He gains a unique skill, Time Reversal, allowing him to rewind three minutes, with unlimited use. Using this, Erik masters game rules, disarms lethal traps, anticipates enemies' moves, and navigates terrifying instances like Eerie Hospital and Devourer's Nest. He uncovers clues between virtual and real worlds, overcomes mockers, rallies teammates, unlocking hidden endings and permissions. Ultimately, he uses his power to turn the tide, winning the final showdown and becoming the game's sole master.
