Love is the most despicable excuse
A series of reported suicides at a hospital and care home on the run-down outskirts of Seoul brings a young female detective, Su-Yeon, and a jaded vampire hunter, Violette, together. The victims were all alone, elderly - forgotten people. When nobody else on the force pays heed to the strange and bloodless nature of the deceased's bodies, these two night owls are forced to work together in a pursuit of justice.
But as the investigation unfurls, it becomes increasingly clear that they, too, are being hunted. . .
Past and present, romance and loneliness intertwine as the investigation to find an ancient, supernatural culprit reveals a landscape of modern isolation in a dark, nocturnal Seoul.
