Kyung-chul is a dangerous psychopath who kills for pleasure. Soo-hyeon, a top-secret agent, decides to track down the murderer himself. He promises himself that he will do everything in his power to take vengeance against the killer, even if it means that he must become a monster himself.

Set in the late 1920s, The Age of Shadows follows the cat-and-mouse game that unfolds between a group of resistance fighters trying to bring in explosives from Shanghai to destroy key Japanese facilities in Seoul, and Japanese agents trying to stop them.
