In Seoul, South Korea, the entertainment industry is teeming with beings of the vampiric variety. Somewhat assimilated into present-day customs and ways of life, these beings navigate the world of showbiz with cautious steps to avoid exposure in a hostile society whose belief in the supernatural has been overwhelmed by the noise of the rational city-people.

Shin Hyejeong is a young, unskilled female vampire in girl group AOA. She hasn't had too much trouble from the mild sorts in the capital and under spotlights. Shin Jimin, of the same reclusive coven, is also a member of the girl group. Having lived among humans all their lives, they are a relatively harmless pair with more familiarity with and affiliation to humankind.

Things are, however, about to get messy for the young vampires with elements of danger and love approaching, on the horizon. While Jimin handles her girlfriend Choa's initiation into the world of the weird and deadly, Hyejeong gets herself tangled in a web of peril as woven by thrill-seeking, cannibalistic vampires in her immediate surroundings. Simultaneously she realises there is more to group-mate and crush Kim Seolhyun, who is at the heart of the chase.
