All 16 episodes of Chimera (2021) — spoiler-light recaps with key plot beats.

EP 01

The Chimera Returns

October 30, 2021

A man named Son Wan-ki picks up a lighter engraved with a strange pattern near a gambling den — and is killed moments later in a car explosion. Detective Cha Jae-hwan arrives at the scene and recognizes it immediately: the Chimera serial murder case from 1984 has come back to life. No one in the department wants to believe him, but the evidence is impossible to dismiss.

EP 02

Convergence

October 30, 2021

A second explosion-linked murder confirms the pattern is real, and pressure mounts to form a special joint investigation team. Jae-hwan crosses paths with FBI profiler Eugene Hathaway, who has flown in from the US with her own classified interest in the case. Neither fully trusts the other, but they need each other. The team takes shape — and so does the growing sense that whoever is doing this has been planning for a long time.

EP 03

The Surgeon’s Secret

November 6, 2021

Surgeon Lee Joong-yeob enters the picture — too calm, too knowledgeable, too unbothered by details that would unsettle anyone else. Jae-hwan can’t place why, but something about this man reads wrong. Meanwhile the team begins to map the 1984 case in parallel to the present murders, and the structural similarities are exact — not a copycat working from memory, but someone who knows the original blueprint.

EP 04

Trail of Fire

November 6, 2021

The forensic deep-dive into the explosive devices reveals something that tightens the investigation considerably: whoever is building these requires formal training in chemistry or biochemistry. Eugene profiles the killer as disciplined, methodical, and almost certainly operating with insider knowledge. The suspect pool narrows — but it also starts pointing toward circles that have the power to make evidence disappear.

EP 05

Buried in 1984

November 13, 2021

Flashbacks pull back the curtain on the original 1984 case — and what the official record left out is significant. Jae-hwan begins to find traces of suppressed evidence, and realizes the people who buried it aren’t historical figures safely in the past. Some of them are still active. Still powerful. And, the investigation is already beginning to look like a threat they’ve dealt with before.

EP 06

Seo-ryun’s Shadow

November 13, 2021

The Seo-ryun Group emerges as the institutional thread connecting 1984 and 2019. Jae-hwan and Eugene press into the conglomerate’s past while reporter Kim Hyo-kyeong runs her own parallel investigation from the media angle — digging at the edges of a story that powerful people have spent decades keeping buried. The deeper they go, the more the present feels like a replay the perpetrator designed rather than improvised.

EP 07

False Suspect

November 20, 2021

A prime suspect is arrested and the team exhales — briefly. The evidence is consistent, the case looks tight, and for a moment it seems like Chimera is done. Then the inconsistencies start surfacing: small things, then larger ones, until the picture becomes clear. Someone constructed this false lead deliberately. The real Chimera has been watching the investigation and playing it like an instrument.

EP 08

Closed Doors

November 20, 2021

Eugene finally opens up about why the FBI assigned her specifically to this case — and the personal history she carries is more tangled with the 1984 murders than anyone on the team knew. At the same time, Joong-yeob’s connection to one of the original victims deepens in ways that complicate his standing: is he a resource, a subject of interest, or something harder to categorize?

EP 09

Blood and Chemistry

November 27, 2021

A new explosion targets someone close to the investigation — and suddenly this is personal. The forensic trail winds into an underground network of individuals with direct ties to both Seo-ryun Group and the original 1984 circle. Jae-hwan is running on something closer to rage than procedure, and Eugene has to keep him from blowing the case while managing her own grief about how close the killer keeps getting.

EP 10

Unmasked, Briefly

November 27, 2021

A partial breakthrough — one layer of the conspiracy peels back and a face becomes visible. But the real Chimera remains further back, operating from a position the team hasn’t fully mapped yet. Jae-hwan starts doubting people around him, reading every person’s history for the angle they haven’t disclosed. Trust collapses in increments, and the show’s paranoid atmosphere reaches peak intensity.

EP 11

Trust No One

December 4, 2021

The alliances inside the special investigation unit fracture under pressure. New evidence points at figures in positions of authority — people who should be assets are now questions. Jae-hwan finds himself in real physical danger, not just professional danger, and the show makes clear that Chimera has no intention of being caught through ordinary detective work. The conspiracy is institutional, not individual.

EP 12

Reporter’s Gambit

December 4, 2021

Kim Hyo-kyeong has enough to publish — a story that would blow the case open and simultaneously endanger her life. Seo-ryun Group escalates its interference in the investigation, and the scope of its reach becomes undeniable. This isn’t a conglomerate protecting financial interests; this is a group that has been managing an ongoing crime for thirty-five years and knows exactly what tools it has available.

EP 13

Origin Point

December 11, 2021

The root of the 1984 explosion traces back to a cover-up orchestrated by a small circle of people — and the episode earns its runtime by making that cover-up feel genuinely horrifying rather than abstractly villainous. Flashbacks and present-day threads converge with increasing urgency. Joong-yeob is running out of runway to keep his personal history hidden, and the final confrontation is beginning to take its shape.

EP 14

The Architect Revealed

December 11, 2021

The identity of the original architect behind the 1984 Chimera plan is finally disclosed — and it lands close enough to the investigation to genuinely shock the team. Joong-yeob’s full history with the case comes out, and the recontextualization of his earlier actions is one of the series’ most rewarding reveals. Everything he’s said and done reads differently now, and the show has earned that pivot.

EP 15

Final Trap

December 18, 2021

Chimera sets a final trap designed to remove all three leads before they can close the case — and it works well enough that all three end up separated and facing life-threatening situations simultaneously. Each trap is built around the killer’s signature method and reflects how deeply Chimera understands each target. The penultimate episode is the series at its most thriller-focused, minimal dialogue, maximum pressure.

EP 16

End of the Myth

December 19, 2021

The true identity of the present-day Chimera is unmasked, and the full chain connecting 1984 to 2019 is laid out completely. The Seo-ryun Group’s decades-long cover-up collapses piece by piece. Jae-hwan and Chimera reach their confrontation; Eugene completes her mission and prepares to return to the US; Joong-yeob finally makes peace with the personal cost the original case extracted from him. Kim Hyo-kyeong broadcasts everything to the public — and the myth of Chimera is put to rest. All three leads part ways, changed by what they found, carrying the kind of quiet that comes after you’ve been right about something terrible for a very long time.

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

The trap collapses before it fully closes. Episode 15 ends with all three leads separated and each facing a version of Chimera’s explosive methodology used as a personal weapon against them — but the finale opens with all three still alive, having survived through a combination of preparation, luck, and the fact that Chimera, for all its construction, ultimately underestimated how much the three had already shared with each other. Jae-hwan had been building toward this confrontation for the entire run; when he finally faces the present-day Chimera directly, it’s not the high-drama standoff the show seems to be building toward. It’s quieter, more forensic — a reckoning between someone who has been haunted and someone who built the haunting deliberately.

The Seo-ryun cover-up unravels completely. The reveal of the present-day Chimera’s identity works because the show has been planting the specific emotional logic behind it for several episodes without ever telegraphing the conclusion. The motivation isn’t greed or ideology — it’s grief that calcified into something systematic. The original 1984 murders were enabled by Seo-ryun Group’s institutional suppression of evidence and witnesses. What the present-day Chimera has been doing is not revenge exactly, but a forced accounting: making the people who benefited from 1984’s cover-up watch the method come back, unable to bury it a second time. The explosions are the same. The pattern is the same. The message is: you cannot keep erasing this.

Lee Joong-yeob’s arc resolves with unexpected tenderness. His full connection to the original 1984 case — the loss that shaped his specific medical expertise, his willingness to be close to this investigation without fully explaining himself — comes into focus in a way that redeems what could have read as narrative withholding. He wasn’t a suspect withholding guilt. He was a survivor withholding grief. In the finale he makes the choice to stop carrying it privately, and his farewell scene with Jae-hwan is the series’ most emotionally complete moment: two people who were never quite partners but shared something heavier than most partnerships allow.

Eugene’s departure is handled with deliberate restraint. She arrived with a mission that was never quite what she disclosed, and she leaves having completed it — but the show is smart enough not to wrap that in false warmth. Her goodbye to Jae-hwan is professional, borderline cool, and the right choice: what they had was a functional alliance built under enormous pressure, not a friendship, and the ending honors that accurately. Kim Hyo-kyeong’s broadcast goes out and the public record is finally corrected. Seo-ryun Group cannot absorb this one. The powerful figures who shaped a cover-up for three and a half decades face consequences the original case never allowed for.

The myth dies; the cost doesn’t. The final images of Chimera are not triumphant. Jae-hwan sits with what he’s found — a solved case that was always solvable, a truth that existed for thirty-five years waiting to be acknowledged — and the show refuses to give him the catharsis that genre convention would normally provide. The killer has been stopped. The conspiracy has been dismantled. But none of the dead are back. The people who chose suppression over accountability had decades of good living while the truth waited. Chimera is, in its final minutes, less interested in the resolution than in the weight of how long it took to get there. Some myths only die when someone is willing to carry the fire that made them — all the way to the end.
