PLOT
Eom Jang-ho, a student of sculpture art, will appear in a folklore presentation hosted by his girlfriend Oh Hyo-jin, a historian. In the process of projecting various folklore materials, she sees a rotten heirloom mask and awakens a certain subconscious mind in the form of the mask. Her story is the story of how a clown dancing in her cloak raped her Thatcher's wife, causing her to plunge into her well. Eomjang-ho, who is engaged in the final practice of her sandae play mask dance, suffers from more vague fear because of her succession mask written on his face. Meanwhile, Oh Hyo-jin, unable to meet Jang-ho after the incident in the auditorium, goes down to the countryside with her classmates as a member of the archaeological excavation team. Even after she begins excavating the archaeological site, she is still depressed and asks if it's because her advisor loves her mother-in-law. She feels that she is in love with her majestic Ho.
