📺 Episode Guide
Spoiler-light recaps for all 12 episodes of Zombie Detective (2020).
EP 01
Dead Man Walking — and Detecting
Sep 21, 2020 · KBS2
Kim Moo Young wakes up as a zombie with no memory of how he died and immediately faces the comedic nightmare of learning to pass as human. He establishes the basic rules of his new existence — raw meat cravings, emotional blankness, a complete inability to feel pain — and begins hiding his condition from everyone around him. Gong Sun Ji is introduced in parallel as someone whose life is also in freefall after leaving her old job, setting the stage for an unlikely partnership.
EP 02
The Assistant He Didn’t Ask For
Sep 22, 2020 · KBS2
Sun Ji becomes more involved in Moo Young’s detective work despite him wanting nothing to do with her, and she starts noticing that his behavior is far too strange to be ordinary eccentricity. The episode leans hard into the comedy of his awkward attempts to mimic human habits — eating, reacting to pain, faking emotions — with Choi Jin Hyuk committing fully to every absurd moment. Underneath the laughs, the mystery around his past begins to expand in ways that suggest there is much more at stake than a simple identity question.
EP 03
Cases Worth Solving
Sep 28, 2020 · KBS2
Moo Young’s private detective work starts intersecting with more serious criminal cases, giving the show a stronger mystery engine alongside its absurdist comedy. Sun Ji proves genuinely useful as an assistant and keeps pushing into situations that complicate his attempt to stay hidden. Their partnership begins to feel less accidental and more necessary — two people at dead ends finding each other’s company oddly essential.
EP 04
Clues That Cut Too Close
Sep 29, 2020 · KBS2
The investigation deepens as clues begin pointing toward connections between current cases and unresolved events from the past. Moo Young’s survival as a zombie becomes harder to manage as his dormant emotions and instincts start reasserting themselves at inconvenient moments. Sun Ji also begins to realize that the answers she is looking for may be tied to people much closer to home than she anticipated.
EP 05
Identity Is More Than a Name
Oct 5, 2020 · KBS2
The story shifts between casework and character revelations, showing how Moo Young’s lost identity affects every decision he makes — both as a detective and as someone trying to exist in a world that technically should not have him in it. Sun Ji grows more determined and starts challenging the systems and people around her. The mystery widens while the drama keeps its balance of absurd humor and real stakes, refusing to let either mode swallow the other.
EP 06
Answers That Only Ask More Questions
Oct 6, 2020 · KBS2
A more complete picture of Moo Young’s past begins to form, but each new piece of information creates more suspicion instead of relief. The detective agency’s work brings them closer to people who may know far more than they are letting on. Sun Ji’s role becomes increasingly active as she tries to protect both the truth and the people she cares about — a combination that is starting to feel impossible to sustain.
EP 07
The Weight of What He Cannot Feel
Oct 12, 2020 · KBS2
The investigation turns more personal, and the emotional cost of Moo Young’s condition becomes harder to ignore even as he physically cannot feel most of it. The show begins linking the zombie premise to broader themes of guilt, memory, and what identity means when everything that defined you is erased. Sun Ji remains the emotional center of the story, keeping him oriented when the truth about his past becomes too heavy to carry alone.
EP 08
Threads That Finally Touch
Oct 13, 2020 · KBS2
Several threads that seemed entirely separate begin to converge, including the larger conspiracy that sits behind Moo Young’s existence as a zombie. The tone grows noticeably more tense as the danger shifts from the comedic problem of hiding his condition to the genuinely frightening question of confronting whoever put him in it. The relationship between the two leads also deepens through shared risk and the kind of trust that only comes from surviving things together.
EP 09
New Complications, Old Wounds
Oct 19, 2020 · KBS2
The story introduces new complications that shake up both the mystery and the detective side of the plot just as things seemed to be settling. Moo Young is forced to deal with the practical and moral limits of being a zombie in a human world — a problem the show handles with more seriousness than you might expect given its tone. Sun Ji continues to act as his anchor as the cases around them become increasingly entangled with his personal history.
EP 10
The Dark Phase
Oct 20, 2020 · KBS2
The investigation reaches its darkest phase as the identity behind the central mystery becomes impossible to avoid any longer. The drama focuses on consequences — specifically the fallout from choices made earlier in the story, especially cases involving the missing and the dead. Moo Young and Sun Ji both move closer to the truth simultaneously, even as that truth threatens to destroy the fragile balance they have built between them.
EP 11
Everything Surfaces
Oct 26, 2020 · KBS2
The remaining secrets finally begin to surface, and the emotional stakes rise sharply for everyone connected to Moo Young’s past. Old relationships, hidden motives, and the larger zombie mystery start lining up for a finale confrontation. Sun Ji’s persistence proves essential in keeping the investigation from collapsing into confusion — and the show makes clear that her loyalty has not been wasted.
EP 12
Who He Was, Who He Is
Oct 27, 2020 · KBS2
The finale. The truth behind Moo Young’s transformation is fully revealed, exposing the people responsible and clarifying exactly how the zombie thread connects to the human crimes running beneath it. His identity crisis reaches resolution as he comes to terms with both who he was before and who he has become — a confrontation that is harder than any of the cases they solved together. Sun Ji’s story resolves through her continued loyalty and courage, giving the pair an ending that leans hopeful without pretending the cost was small.
🏁 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 Zombie Detective. Stop here if you haven’t finished the series.
The conspiracy was never really about the undead. The final episode reveals that Moo Young — originally Kang Min Ho, a man with a dangerous past and dangerous enemies — was killed by people who had reason to bury both him and what he knew. The zombie resurrection is not framed as supernatural accident but as the consequence of something specific and cruel, and the final arc forces Moo Young to face not just who killed him but why. The confrontation is sharp and direct, and the show wisely does not let the absurdist premise undercut the emotional weight of what it means to reclaim a life you lost.
Sun Ji’s role in the finale is not decorative. Her persistence throughout the series — the stubborn insistence on following every thread even when Moo Young asked her to stop — is precisely what allows the truth to come out before it can be buried again. She is not saved by him at the last moment; she saves herself, and in doing so, she provides the opening he needs. It is one of the more quietly satisfying dynamics in the drama, and the finale honors it without making a speech about it.
The ending chooses hope without choosing easy. The people responsible are exposed and the central conspiracy is dismantled, but Zombie Detective does not pretend that returning to life — even in this strange, undead way — erases the damage that was done. Moo Young accepts both the man he was and the version of himself he has built episode by episode through detective work, bad habits, and an assistant who refused to leave. The final image gives them a future without spelling it out completely, which is exactly the right call for a show that always knew when to let the absurd speak for itself.
✍️ KDramaWorlds Editor’s Take
Our honest read on why this drama is worth your time — and who it’s for.
🧟 Undead Comedy🔍 Mystery Engine💙 Unexpected Heart😂 Genuinely Funny
Zombie Detective is a premise that should not work as well as it does. A man wakes up as a zombie, has no memory, decides to become a private detective — this is exactly the kind of logline that collapses under the weight of its own concept about three episodes in. But writer Baek Eun Jin and Choi Jin Hyuk find something real inside the absurdity: a story about a person trying to reconstruct an identity from scratch, using only the cases in front of him and the increasingly indispensable woman who refuses to be his ex-assistant. The comedy is physical and committed, the mystery is structured with more care than the premise suggests, and the whole thing moves quickly — at 35 minutes per episode, it never overstays its welcome. It is also, quietly, a drama about what it means to be human when you are no longer technically sure you qualify.
The show is not flawless. The supporting cast is uneven — some characters work beautifully in the comedic rhythm the show establishes, while others feel underdeveloped in ways that become more obvious once the conspiracy layer kicks in. The tonal shifts between broad comedy and genuine thriller can occasionally feel abrupt rather than purposeful, and a couple of the mid-series episodes could have trimmed their case-of-the-week elements without losing anything important. But these are complaints about a drama that is otherwise doing exactly what it set out to do. Fans of Flower of Evil looking for something tonally lighter, or viewers who bounced off the grimness of All of Us Are Dead and wanted something more playful in the zombie space, will find this scratches an itch neither of those dramas could.
What lingers is Choi Jin Hyuk’s performance — a comedian doing detective-drama work inside a zombie costume, committed to the physical comedy while never letting it swallow the character’s emotional throughline. Park Ju Hyun matches him scene for scene as Sun Ji, smart and stubborn in ways that complement rather than duplicate his energy. Together they make something that is genuinely fun to watch, which is not a small thing. Zombie Detective is a short, weird, surprisingly earnest drama about finding yourself — even if yourself turns out to be someone you did not particularly choose to be.

⚖️ Final Verdict
What works

What to know first
•The tonal shifts between comedy and thriller can feel uneven in the middle stretch
•Supporting characters are mixed — some charming, some thin
•Not for viewers expecting serious crime procedural or genuine horror
•A single-season, completed story — no cliffhanger, no Season 2 to wait for
8.1 / 10A clever, compact, and genuinely funny genre mashup — watch it when you need something weird that actually works.
