On a misty night in late autumn, eleven men and women who were cursed were led by a white lantern to the nameless solitary tower, the "Infernal Affairs Pavilion". The faceless landlord in front of the door sets down a rule: before the rooster crows, you must find the door with your own cause and effect engraved on it. The struggling Nuo noodles in the mirror, the Gu puppets sewn into flesh and blood, the fragrant fox rouge... Behind every door is an eternal prison tailor-made for them. When cause and effect intertwined and reincarnation started, they discovered that the attic itself was a living hell feeding on sin. If you push this door open, you will never be reincarnated; if you don't push it, your soul will fly away...
