A newly married couple moves into a secluded, luxurious mansion and invites several friends and colleagues over to celebrate their housewarming. Unbeknownst to the residents, the mansion is haunted by Xiao Xuan (Ruby Wong Jo-Yi), a vengeful female spirit driven by lingering hatred from her past life. Targeted by her grudge against unfaithful and womanizing men, the ghost uses seduction, illusion, and supernatural force to target male guests during the night, provoking chaotic sexual encounters, jealousy, and life-threatening terror inside the mansion.
