For a long time, the battle between humans and vampires has never stopped. Many years later, in order to survive, humans live in cities tightly controlled by the church and train demon hunters to protect themselves. After the war with vampires ended, the demon hunters were disbanded and gradually forgotten by the world. The legendary demon hunter priest (Paul Bettany) who had made great contributions during the war had been hiding for many years, but the sudden visit of Sheriff Hicks (Cam Gigandet) from Augustine brought him bad news. His relatives far away were attacked by vampires and his niece Lucy was abducted. In order to rescue his relatives, the priest did not hesitate to go against the will of the bishops and embarked on his own journey of salvation. At this time, because of the violation of the will of the bishop, the bishop sent four demon hunters to hunt down the legendary priest... This film is adapted from the comic work "Priest" by the Korean cartoonist Xing Minyou, which is widely acclaimed in the United States.
