Park Jun-mo is the protagonist of The Worst of Evil, a low ranking detective from the countryside who is selected for a dangerous undercover assignment. Tasked with infiltrating the Gangnam Union, he must shed his identity as a police officer and pass himself off as a rising figure in the criminal world, an assignment that demands nerve, improvisation, and a willingness to commit fully to the role.

Caught between his mission, his marriage, and the men who consider him a brother, Jun-mo is steadily worn down by the moral cost of deception and the constant threat of exposure.
