In a time long past, twelve angels of the zodiac fought tenaciously against the forces of evil to protect humanity. Through heroic sacrifice, the angels managed to seal the dark forces at the gates of Hell, bringing peace to the world.
However, the tranquility did not last long. Evil has risen again, causing chaos among humans. In the face of the threat of a group of evil beings, including O-Gwi (Park Hyung-sik).
