Beyond Evil sends two mismatched detectives back into a case that never really closed, twenty years after it first shook a quiet South Korean town.

What is Beyond Evil about?

A fresh murder pulls a small, orderly city back into the shadow of a serial killing spree from two decades earlier, one that permanently altered detective Lee Dong-sik's life. Paired against his will with a transfer from Seoul, Dong-sik has to relive a history he would rather bury while working alongside someone who arrives with his own hidden motives. The series moves at a patient pace, letting old grudges, local secrets, and shifting alliances build pressure between the two men long before any answer to the murders. Unmasking the person behind the killings turns out to be only half the story.

About the cast

Shin Ha-kyun anchors the show as the town's veteran investigator, with Yeo Jin-goo playing the outsider forced into an uneasy partnership with him. Choi Dae Hoon, Choi Sung-eun, Kim Shin Rok, Cheon Ho-jin, Park Ji Hoon, and Choi Jin-ho round out an ensemble built for slow-burn drama rather than procedural shorthand, giving the small-town setting a lived-in feel that carries the story's tension between its bigger plot turns.

Context & significance

Directed by Sim Na-yeon, Beyond Evil arrived in 2021 as part of a wave of Korean crime dramas that trade fast twists for atmosphere and character detail. Its central pairing of a local detective and an outside investigator gives the eight-episode run room to dig into class tension and small-town memory alongside the central mystery. The show was strongly reviewed on release, praised for its patience and for treating its two leads as fully drawn people rather than simple hero and suspect.
