Dr. Cheon and the Lost Talisman

Dr. Cheon, a grandson of a powerful shaman, does not actually believe in ghosts and performs fake exorcisms as a way of living. However, Dr. Cheon gets more than he has bargained for when a client shows up asking him to handle a powerful possession case. He begins to question everything he has ever believed in as a series of abnormal and mysterious events starts to happen, forcing him to face resurfacing childhood horror he has been trying to forget. Having to work together with an unusual group of heroes, will Dr. Cheon be able to overcome the challenges and reconnect with his spiritual heritage?
