A risqué X-ray causes a scandal in a hospital in Seoul. A nurse thinks that she and her boyfriend are depicted in the X-ray, and decides to quit her job. The next day, the hospital is deserted. Everyone has called in sick, except for two women: the nurse and the head doctor. This event is the starting shot for a strange, episodic story about confidence and faith, with an emphasis on nurse Yoon-Young's relationship.
Maggie is an idiosyncratic debut in which, for example, the titular lead proves to be a talking, prescient catfish. Inexplicable sinkholes appear throughout South Korea and the nurse’s lazy boyfriend is put to work filling them. The film is as exciting as actress Lee Jooyoung, who plays Yoon-Young, for which she received the Best Newcomer of 2018 prize at the Busan film festival.
