Like a hellhound driven mad by the thrill of the hunt, pitiless serial killer Jang Kyung-chul prowls Seoul's ill-lit streets, searching for the next victim. Of course, no one is safe when the human-like monster is out for flesh. Jang's favourite prey, however, is unaccompanied ladies. But someone must end the murderer's reign of terror. When an innocent mother pays in blood, elite agent Kim Soo-hyun has no choice but to step up in the name of justice. However, he is about to play with fire: as the determined officer embarks on a dangerous mission to bring down the psychopath behind the law's back, a destructive transformation gradually occurs. After all, if you stare into the abyss, darkness stares back. Now, reason and pleas for mercy won't work. Because, in this world, some monsters are more horrifying than others. And when blind revenge rules the mind, what separates man from beast?
