South Korea in the 1990s becomes the backdrop for The Worst of Evil, a crime drama series built around an undercover officer whose infiltration of a sprawling drug syndicate puts his own marriage on the line.
What is The Worst Evil about?
Set against the backdrop of a South Korea in the middle of rapid change, the series follows a police officer who goes undercover to work his way inside a large-scale crime syndicate moving illegal drugs across South Korea, China, and Japan. The deeper he embeds himself, the harder it becomes to separate the role he is playing from the life he actually leads, and the show tracks the toll that double life takes on him scene by scene. Complicating matters further, his wife works as a narcotics officer, which means the investigation he is buried in and the one she is running from the outside are pulling in the same direction from opposite sides of the law. The series builds its tension less from a single big reveal and more from the accumulating pressure of two people, bound to each other, operating on either side of a case that could end either of their lives.
About the cast
Ji Chang-wook leads the series in the undercover role, with Wi Ha-jun, Lim Se-mi, Im Sung-jae, Geum Gwang-san, Cha Rae-hyung, and BIBI in the supporting cast. Directors Han Dong-wook and Park Geun-buem share duties on the series, giving it a consistent visual approach across its run of roughly 42-minute episodes.
Context & significance
The Worst of Evil belongs to a strong run of South Korean crime dramas that use undercover-operation stories to examine institutional pressure and personal cost, a genre that has found a wide international audience in recent years. Its 1990s setting places it in a period of significant transformation for South Korea, and the series uses that backdrop as the world its characters move through rather than as a subject in its own right. The show has drawn a strongly favorable critical reception since its release, a rare feat for a series balancing procedural detail with sustained emotional stakes.
