A cynical detective who has long stopped believing in people, and a pastor who is convinced that there is a light in everyone, team up to reopen a closed case involving the death of a homeless man.
Son Yohan does not want to return to the old investigation, but the evidence brought by Yu Chinsin brings a forgotten past back to the surface.
This murder marks the beginning of a series of grim discoveries—and blurs the boundaries between victim and executioner, as well as between those who once wanted to believe in people.
Detective Son Yohan has long since lost his illusions: for him, there is no absolute evil or absolute good—only a murky, dirty-gray truth. His complete opposite is Yu Chinsin, a former forensic pathologist who now serves as a pastor on weekends and runs a coffee shop on weekdays—yet he still sees good in people. One day, he shows up at the station and asks for the closed case of a homeless man’s death to be reopened, convinced that the official version is too simple. Son Yohan does not want to get involved, but the clues brought by the pastor trouble his memory and force him to look at the past differently. At first glance, an unremarkable crime sets off a chain of unpredictable events and leads to truly monstrous revelations.
