After a nearly fatal hit-and-run accident, the young girl, Young-shin, becomes unresponsive and sinks into a deep coma. However, the experienced priest, Father Kim, strongly believes that the helpless girl is possessed by an ancient evil form, and as a result, he enlists the help of the rebellious young seminarian, Choi, to complete the challenging purification ritual. As the mismatched duo tries to set free the poor human host from the suffocating stranglehold of the nameless malevolent spirit, strange events will put their faith to the test. Can the exorcists release the girl from the powerful demon?
