Dr. Cheon and the Lost Talisman

In a village where the eldest son traditionally serves as the protector against supernatural threats, Dr. Cheon, the current heir, is a skeptical exorcist who does not believe in ghosts. Instead of genuine spiritual work, he uses his sharp understanding of human psychology to perform staged exorcisms and solve cases brought to him. One day, Yoo-kyung, a woman who claims she can see ghosts, approaches Dr. Cheon with a compelling request. Accompanied by his assistant In-bae, Dr. Cheon visits Yoo-kyung's home, where they encounter a series of unusual and unexplained events. As they investigate these occurrences, they begin to uncover the hidden history and significance of a mysterious talisman called 'Seolkyung.'
