In Seoul 2015, a girl displays strange symptoms after a hit-and-run. Having gotten into trouble with the church due to frequent, unexpected behavior, Priest Kim has his own plans for saving the girl despite opposition and suspicion from everyone around him. To proceed with his plan, he needs another priest with the right credentials, and while most seem to avoid him, seminarian and deacon Choi is given the mission to help and spy on Kim. Eventually, they have only one day to save the girl, so Priest Kim and Deacon Choi perform a life-threatening ritual. Based on the short film, 12th Assistant Deacon, which won awards at both the Mise-en-scène Short Film Festival and Jeonju International Film Festival, The Priests has been made into a feature-length film by the same director. It is also a creative adaptation of The Exorcist by William Friedkin, adapted to Korean circumstances. Rookie actress Park Sodam gives an impassioned performance as the girl, while Kim Yunseok and Kang Dongwon convincingly play the opposing characters of Priest Kim and Deacon Choi.
