Shasi, who inherited the Mary's Inn Hotel from his father, faced a big problem: A ghost named Mary interrupted the old hotel. During his life, Mary committed suicide because of a broken heart because the bridegroom did not come to their wedding. For the sake of the sustainability of his hotel business, Shasi hired a group of ghost hunters to drive away Mary forever. During the process of exorcism, Mary fought and entered Shasi's body, and made everything chaotic.
