S1E6 Revenge Him

Hwa Pyeong and Mateo manage to stop the possessed woman, Kim Yoon Hee, from killing someone—or so they believe. When the police discover her boyfriend’s dead body in a parking lot, she becomes the main suspect. Detective Kang returns to the hospital to take her into custody, but she has already vanished. Now the detective and the exorcist duo must track her down and drive out the demon before she commits something truly terrible.
