Imagine waking up in a garbage dump with no memory, no idea who killed you, and one very significant new problem: you are dead.
Well, technically, undead.
Most television zombies would respond to this development by stumbling toward the nearest population center and beginning the apocalypse. Kim Moo-young has more practical concerns. He needs to figure out who he was, how he died, how to walk like a normal human being, and—perhaps most urgently—how to earn enough money to buy food.
Welcome to Zombie Detective, the 2020 Korean mystery-comedy that looked at decades of zombie mythology and apparently asked the question nobody else was brave enough to ask:
What if the zombie was the detective?
The result is wonderfully ridiculous. There are murders, mysteries and genuine danger, but there is also a zombie desperately attempting to pass as an ordinary handsome Korean man while navigating one of the greatest indignities ever inflicted upon the undead: capitalism.
And somehow, it works.
First, Our Zombie Has to Learn How to Be Human
Kim Moo-young, played by Choi Jin-hyuk, wakes up after being killed and buried, only to discover that medical waste has somehow brought him back as a zombie. Unfortunately, resurrection does not come with an instruction manual. It does not even come with memories.
He has no idea who he used to be or who killed him. KBS describes him as an unidentified dead man who eventually assumes the identity Kim Moo-young and becomes a “zombie detective” while trying to uncover his past.
But before he can investigate his own murder, he has to master something considerably harder: pretending not to be a zombie.
And this is where Zombie Detective realizes exactly how funny its premise can be.
Moo-young essentially has to retrain his body to behave like a human. Zombies aren’t exactly famous for graceful movement, sparkling conversation or appropriate reactions to social situations. He has to disguise his appearance and control his decidedly undead tendencies because walking into town looking like a corpse would probably complicate the whole detective career.
The series could have made him a terrifying supernatural antihero. Instead, it gives us something much better: a zombie having an existential crisis because fitting into human society is exhausting.
Honestly, relatable.
He Doesn’t Hunt Humans. He Hunts Criminals
Eventually, Moo-young takes over the identity—and detective agency—of a private investigator and begins investigating cases while quietly pursuing the biggest cold case of all: himself.
Who was he before he died? Why was he murdered? Who was responsible for his resurrection? And is there any possibility that he can understand what happened to him?
Those questions provide the mystery running underneath the comedy. This isn’t simply a collection of zombie jokes stretched across a television season. There is an actual investigation driving the story, and Moo-young’s missing past gives the series enough suspense to keep pulling you into the next episode.
Then Gong Sun-ji arrives.
Played by Park Ju-hyun, Sun-ji is a former investigative television writer with precisely the personality you do not want hanging around when you’re secretly a member of the walking dead. She’s persistent, curious and extremely willing to stick her nose into things that probably should be left alone.
Naturally, she ends up working with Moo-young.
Their partnership turns Zombie Detective into an odd-couple investigative comedy: one person is determined to uncover the truth, while the other would very much like to uncover the truth without anyone uncovering the fact that he has no pulse.
The Best Joke Is That Being a Zombie Is Incredibly Inconvenient
One reason Zombie Detective works is that it doesn’t treat zombiehood exclusively as a source of horror. It treats it as a logistical nightmare.
Zombie movies normally skip over the mundane questions. How does an undead person pay rent? How do you disguise decomposing skin? How do you interact with people without accidentally revealing that you are biologically incompatible with the concept of being alive?
And most importantly: what does a zombie eat when eating humans is absolutely off the table?
Moo-young is not trying to become the next great monster of Korean television. He’s trying to function.
That reversal gives the show much of its charm. Instead of humans desperately trying to survive zombies, we have a zombie desperately trying to survive humans.
There are moments when you almost start feeling sorry for him. He was murdered, resurrected without his memories and dumped back into society, where he quickly discovers that being undead apparently does not exempt anyone from needing money.
Death couldn’t even get him out of having a job.
Choi Jin-hyuk Is Fully Committed to the Absurdity
A premise this ridiculous only works if the actor playing the zombie commits to it, and Choi Jin-hyuk understands the assignment.
The actor had already built a résumé packed with dramas including The Heirs, Emergency Couple, Tunnel and The Last Empress. Zombie Detective gives him a very different challenge: he has to play Moo-young as simultaneously intimidating, confused, miserable and completely hilarious.
KBS’s own character description makes the contradiction part of the joke. Moo-young disguises his zombie appearance and presents himself as an attractive man, but underneath that exterior is a skeptical undead neat freak who has developed a rather low opinion of humanity.
Choi plays the physical comedy especially well because Moo-young isn’t supposed to feel like a comedian telling jokes. He is frequently deadly serious about completely absurd problems.
That distinction matters. Moo-young thinks he is starring in the tragic mystery of his own death.
Unfortunately for him, everyone else is starring in Zombie Detective.
Park Ju-hyun Gives Him the Perfect Human Problem
If Moo-young’s goal were simply to remain unnoticed, Gong Sun-ji might qualify as his natural predator.
Park Ju-hyun gives the series the human energy it needs. Sun-ji is bold enough to charge toward mysteries rather than away from them, creating a very useful detective partner and an absolutely terrible person to have nearby when you’re concealing a supernatural secret.
The chemistry comes from that imbalance. Moo-young has spent considerable effort learning how to blend into society. Sun-ji has the kind of personality that keeps dragging him toward situations where blending in becomes increasingly difficult.
And because this is a mystery-comedy rather than a straight sitcom, their investigations can suddenly become surprisingly serious. Zombie Detective is happy to be silly, but it doesn’t abandon the crime and thriller elements promised by the word “detective” in its title.
That mixture keeps the series from becoming predictable.
This Is the Zombie Show for People Who Don’t Want Another Apocalypse
Perhaps the biggest reason to recommend Zombie Detective is that it does something genuinely different with one of entertainment’s most overworked monsters.
Korean film and television already had some spectacularly terrifying interpretations of zombies by the time this series arrived. Train to Busan turned them into a claustrophobic nightmare. Kingdom dropped them into a historical political thriller.
Zombie Detective decided the undead had suffered enough.
There is no need to spend every episode preparing for civilization to collapse. This is a smaller, stranger and much sillier story about one zombie attempting to understand his death while discovering how bizarre human life looks when you’re technically no longer part of it.
The mystery gives you something to solve. The thriller elements give the story stakes. The supporting characters bring additional chaos. But the comedy is what makes the series such an easy recommendation, particularly if you want supernatural entertainment without spending 12 hours watching humanity scream.
It is a zombie drama that understands something very important:
Sometimes you don’t want the zombie to eat the detective.
Sometimes you want the zombie to open a detective agency.
It Even Picked Up an Award
The show’s unusual approach received some recognition at home. KBS World notes that Zombie Detective won the Best Challenge Award at the 2020 KBS Entertainment Awards.
Choi Jin-hyuk was also nominated for the Excellence Award for Actor in a Miniseries at the 2020 KBS Drama Awards.
Considering that the role required him to convincingly portray a murdered man resurrected by medical waste who disguises himself, becomes a private investigator and attempts to coexist with humanity, “challenge” feels like a particularly appropriate word.
Should You Watch Zombie Detective?
Absolutely—especially if you like K-dramas that are willing to get weird.
Don’t go into Zombie Detective expecting Train to Busan levels of terror. This isn’t really interested in making you afraid of its zombie. Half the time, you’ll probably want to buy him dinner.
Watch it for Choi Jin-hyuk’s wonderfully committed performance, Moo-young and Sun-ji’s increasingly chaotic partnership, the mystery surrounding his death and a story that can jump between crime investigation, supernatural thriller and ridiculous comedy without losing its identity.
Most of all, watch it because there are thousands of detective shows and thousands of zombie stories.
There are considerably fewer shows about a handsome zombie private investigator who has to conceal the minor professional complication that he is a corpse.
Take originality wherever you can get it.
