Lee Dong Sik (Shin Ha-kyun) has spent two decades as the most hated man in Manyang. A detective stripped of his rank and confined to small-town duty, he carries the unspoken accusation that he murdered his own twin sister, Yu Yeon — whose body was never found. When a new string of murders begins to mirror the cold cases that broke the community apart, elite Seoul detective Han Joo Won (Yeo Jin-goo) arrives at the Manyang Police Substation with one conviction: Dong Sik is the killer, and he will prove it.

What follows is not a straightforward hunt. As Joo Won and Dong Sik are forced into an uneasy partnership, the layers of Manyang’s history — corruption buried in police records, political favors traded over unmarked graves, and secrets that several powerful people have spent years protecting — begin to surface. Both men will have to ask themselves the same question the drama asks of every viewer: what separates justice from monstrousness, and how far are you willing to go to find out?

📺 Episode Guide

Spoiler-light recaps — enough to remember where you left off, nothing that ruins the ride.

Beyond Evil Episode 1 — The Appearance
EP 01
The Appearance
February 19, 2021
Elite detective Han Joo Won arrives at the Manyang Police Substation with one fixed idea: the eccentric, demoted Lee Dong Sik is a killer. A skeleton found in the reed fields reignites a town still haunted by twenty-year-old murders, and the two men begin their tense, combative partnership. The atmosphere — grey, damp, loaded — is established from the first scene.

Beyond Evil Episode 2 — The Disappearance
EP 02
The Disappearance
February 19, 2021
The skeletal remains are identified, raising fresh questions about Manyang’s violent past. Jin Mook’s daughter Min Jung has gone missing, and Joo Won faces pressure from his powerful father — Police Superintendent Han Gi Hwan — to keep things quiet. Dong Sik visits his mother at a nursing home and the episode deepens the portrait of a man who has been enduring rather than living.

Beyond Evil Episode 3 — The Suspicion
EP 03
The Suspicion
February 26, 2021
Missing case files mysteriously return — someone is watching the investigation from the inside. A cellphone found in the woods implicates Joo Won in ways he can’t easily explain. Councilwoman Do Hae Won begins exercising her political weight. By the end of this episode, nearly every adult in Manyang looks guilty of something.

Beyond Evil Episode 4 — The Arrest
EP 04
The Arrest
February 26, 2021
Blood linked to a missing woman surfaces at the butcher shop. Dong Sik is arrested for Min Jung’s kidnapping — and the town, including officers who know him, rallies for his release while Joo Won holds firm. The episode exposes how easily circumstance can destroy someone, and how willingly institutions allow it.

Beyond Evil Episode 5 — The Trap
EP 05
The Trap
March 5, 2021
Dong Sik walks free when Jung Je provides an alibi, but Joo Won defies his father and goes public about a serial killer operating in Manyang. CCTV footage implicating Ji Hoon surfaces, and the investigation opens new questions about Jung Je’s history — a mental institution stay and behaviour that no one in the town has ever fully explained.

Beyond Evil Episode 6 — The Cover-Up
EP 06
The Cover-Up
March 5, 2021
Flashbacks show Jin Mook watching his daughter and Jung Je from a distance — and the shape of what he knew begins to emerge. Joo Won discovers that CCTV footage in the records room has been wiped. Lee Chang Jin is holding dashcam footage as personal insurance, and the leaked video sets off a chain reaction inside the station that nobody is ready for.

Beyond Evil Episode 7 — The Message
EP 07
The Message
March 12, 2021
Dong Sik reveals he has been hiding Min Jung’s cellphone near Jae Yi’s butcher shop. He sends a chilling text to Jin Mook using it. Flashbacks show he found something in Jin Mook’s supermarket basement that no one should ever have to find. The police converge. The episode’s final minutes are the first real gut punch of the series.

Beyond Evil Episode 8 — The Confession
EP 08
The Confession
March 12, 2021
The autopsy’s finding — that Min Jung was buried alive — is devastating. Under interrogation, Jin Mook breaks. He confesses where the other bodies are buried. And then he says four words that change the entire case: he did not kill Yu Yeon. The episode’s final revelation blows the drama open in a direction no one fully anticipated.

Beyond Evil Episode 9 — The Discovery
EP 09
The Discovery
March 19, 2021
Three months pass. Jin Mook has died by apparent suicide in his cell, leaving Dong Sik a message that insists on his innocence. Bodies are found on land belonging to Lee Chang Jin, and suspicion around the suicide deepens. Dong Sik tears Jin Mook’s house apart searching for answers that feel more elusive than ever.

Beyond Evil Episode 10 — The Truth Beneath
EP 10
The Truth Beneath
March 19, 2021
Yu Yeon’s body is found buried in Dong Sik’s own basement. The blow is total. Joo Won plants evidence to frame Chief Nam for aiding Jin Mook’s suicide — a morally compromising act the drama refuses to let go easily. The autopsy of Yu Yeon’s body reveals she was not strangled. The fractures suggest she was hit by a vehicle.

Beyond Evil Episode 11 — The Death of Chief Nam
EP 11
The Death of Chief Nam
March 26, 2021
Chief Nam is kidnapped and killed. Jung Je’s visions of Yu Yeon on the night she disappeared suggest he witnessed something he has never spoken about. Gil Go’s secret prison visit to Nam hints at a conspiracy reaching deep into the town’s political and police leadership. Joo Won finds Nam too late, despite giving chase.

Beyond Evil Episode 12 — The Night of Yu Yeon
EP 12
The Night of Yu Yeon
March 26, 2021
The pivotal flashback arrives. Jung Je argued with Yu Yeon about keeping their relationship from Dong Sik. She fled — and was struck by a car driven by Chief Superintendent Han Gi Hwan. Lee Chang Jin arrived and witnessed everything. Jung Je, fragile and disoriented, is brought by Joo Won to Dong Sik’s basement as the truth takes its final shape.

Beyond Evil Episode 13 — The Conspiracy Unravels
EP 13
The Conspiracy Unravels
April 2, 2021
The cover-up is exposed in full: Councilwoman Do bribed Chang Jin, Superintendent Jung, and Gil Go for over twenty years to protect her son Jung Je. Joo Won attends his father’s commissioner hearings while simultaneously leaking corruption evidence to the press. Dong Sik accepts a new post — not because the case is over, but because his plan is not.

Beyond Evil Episode 14 — The Recording
EP 14
The Recording
April 2, 2021
Jung Je tricks Chang Jin into disclosing crucial details about the night Yu Yeon died, with Dong Sik listening over the phone. Chang Jin implicates both Councilwoman Do and Han Gi Hwan. Joo Won is arrested by Dong Sik for the death of Lee Geum Hwa — and the drama refuses to let either man stand outside the moral reckoning it has been building toward.

Beyond Evil Episode 15 — The Final Pieces
EP 15
The Final Pieces
April 9, 2021
A recording captures Han Gi Hwan confirming he struck Yu Yeon with his car and orchestrated the cover-up. Joo Won hears his father dismiss him as a liability — and shatters. In the rain, on his knees, he begs Dong Sik for help. Chang Jin’s attempt to silence Superintendent Jung fails. Joo Won visits Jung’s house alone. He comes back with blood on his hands.

Beyond Evil Episode 16 — Finale
EP 16
Finale
April 10, 2021
The full truth reaches the surface. Ji Hwa confronts Dong Sik and finally learns what he has known all along about Han Gi Hwan. Sentences are delivered: Gi Hwan receives 20 years; Chang Jin, life; Councilwoman Do, 9 years; Jung Je, 3 years; Dong Sik, 1 year with probation. Joo Won is acquitted. A quiet epilogue set in February 2022 finds all four survivors sharing a meal — bittersweet, hard-won, and earned.

🏁 Ending Explained

Full spoilers ahead — everything that happens in the finale and what it all means.

⚠️
Spoiler Warning — This section covers the full finale of Beyond Evil. Stop here if you haven’t finished the series.

The truth was never buried — it was protected. The finale of Beyond Evil is not a sudden revelation but the final weight of everything the drama has been slowly stacking for sixteen episodes. Ji Hwa confronts Dong Sik, and he finally speaks the truth he has carried for twenty-one years: it was Chief Superintendent Han Gi Hwan who struck Yu Yeon with his car on that night in 2000, and it was an entire web of powerful people — police, politicians, a grieving mother — who helped him disappear it.

Beyond Evil (2021) Episode 15 — The Final Pieces

Sentences are delivered — and none of them feel like justice. Han Gi Hwan receives 20 years. Lee Chang Jin is sentenced to life. Councilwoman Do gets 9 years for concealing Jin Mook’s crimes in exchange for protecting her son. Jung Je receives 3 years for his role in the events of that night. Dong Sik himself receives 1 year with 2 years of probation — not because he was innocent of everything, but because the law can only see so far into what surviving two decades of false accusation does to a man. Joo Won is acquitted entirely for his role in uncovering the truth, the drama making clear that his methods — however morally complicated — were ultimately in service of something real.

What Joo Won releases is the thing that cannot be taken back. The recording of Han Gi Hwan and Lee Chang Jin — captured by the bug Joo Won planted in the car — goes to public media. It confirms not just guilt, but the texture of the cover-up: two men in a car casually discussing a life they destroyed, a name they buried, and the calculations they made to keep power. Joo Won’s decision to release it rather than use it as leverage is the moment the drama has been asking him to choose — between his father’s world and Dong Sik’s.

Beyond Evil (2021) Episode 8 — The Confession

The epilogue earns its warmth precisely because the drama never pretended things would be clean. It is February 2022. Joo Won has been reassigned to the Women and Juvenile Affairs Division — a demotion that carries its own quiet commentary on how institutions absorb men who break from them. On the anniversary of Chief Nam’s death, he visits Yu Yeon’s grave. Then he goes to meet Dong Sik, Ji Hwa, and Jae Yi for a meal. Four people who survived the same disaster, sitting at the same table. Not healed. Not whole. But present — and that, the drama argues, is what counts.

The question the drama leaves you with is not who the monster was. It was always Han Gi Hwan and the system that protected him. The real question — the one Dong Sik and Joo Won have been circling since episode one — is what it costs to become the person who faces that. Both men paid. Both also, in their way, survived. Beyond Evil isn’t a story about justice arriving. It’s a story about what two damaged men chose to do when they finally had the same truth in their hands.

✍️ KDramaWorlds Editor’s Take

Our honest read on why this drama is worth your time — and who it’s for.

🕵️ Psychological Tension🌧️ Atmospheric & Grey💔 Earned Bromance⚖️ Morally Unresolved

Beyond Evil is the kind of drama that trusts you to sit with discomfort. It opens slowly — deliberately, almost provocatively so — and for the first few episodes it’s easy to mistake patience for stagnation. What it’s actually doing is building two portraits of men who have been permanently altered by a town’s capacity for looking away. Shin Ha-kyun’s Dong Sik is a masterclass in playing someone who has learned to weaponise being underestimated. Yeo Jin-goo’s Joo Won is the counterweight: polished, principled, convinced of his own clarity — and slowly stripped of every certainty he arrived with. The dynamic between them is the engine of the entire drama, and it never loses its charge.

Beyond Evil (2021) — cinematic still

What sets Beyond Evil apart from comparable thrillers like Through the Darkness is how thoroughly the corruption is embedded — not as a backdrop or twist, but as the tissue of everyday life in Manyang. The killer is almost beside the point. What the drama is really excavating is how power protects itself, how communities enable silence, and how the people who break that silence pay in ways the law rarely accounts for. Kim Soo-jin’s writing is meticulous and unusually honest about the costs on every side. Very few K-thrillers are willing to put the two lead characters in the position this one does by episode 14.

The ending will divide people who wanted a cleaner moral ledger — and that division is the point. Beyond Evil earns its reputation not despite the ambiguity but because of it. It is not comfortable, it does not offer easy catharsis, and it asks you to hold two contradictory things at once: that what Dong Sik and Joo Won did was necessary, and that it came at a cost that doesn’t simply dissolve when sentences are handed down. One of K-drama’s finest psychological thrillers — watch it for the performances, stay for the ending that has genuinely earned its weight.

👍👍👍 BEST FOR 👍👍👍
🕵️ Fans of slow-burn psychological crime dramas
🏆 Viewers who appreciate award-calibre acting
🌑 Those who don’t need a clean moral resolution

⚖️ Final Verdict
What works
Shin Ha-kyun’s haunted, career-defining performance as Dong Sik
The hunter-becomes-suspect dynamic, executed with rare precision
Systemic corruption woven into every layer — never just a backdrop
One of the most satisfying, earned finales in K-thriller history

What to know first
The first three episodes are deliberately slow — don’t tap out early
A large ensemble of suspects can be difficult to track in early episodes
Heavy thematic weight throughout — not comfort viewing
The ending rewards patience but offers ambiguity, not clean closure

8.7 / 10Sit through the slow start — everything from episode 7 onward is some of the finest K-drama ever made.
