Just when you think Mr. Kim can’t get any closer to Min-ji, Agent Kim Reactivated Episode 5 yanks the rug out from under him, and us. This is the episode where the show finally cracks open its central mystery, and honestly, it does it while keeping its foot on the gas the entire time. So Ji-sub’s ex-spy dad is bloodied, betrayed, and somehow still standing, and by the end of it, I was gripping my remote a little too hard.
Let’s get into everything that went down.
A Little Girl Who Ran Away: The 2014 Flashback That Sets the Tone
The episode opens not in the present chaos, but back in 2014, with a young Min-ji and Mr. Kim moving into a new house. Han-su and Park Jin-cheol are there helping out, but Min-ji slips off to the playground with a few neighborhood kids without telling her dad. From there, she wanders into the Jeilwon Senior Welfare Center to hide, falls asleep, and gets accidentally locked inside.
She eventually escapes through a window with help from a passing high schooler and makes her way home, right into a frantic, relieved Mr. Kim, who was clearly losing his mind looking for her. He tells her never to wander off alone again, and then breaks down crying. It’s Min-ji, the child, who ends up comforting him.
It’s a small moment in the grand scheme of the episode, but it does a lot of quiet work. This isn’t the first time Min-ji has vanished on her father, and it isn’t the first time he’s fallen apart because of it. That history makes the present-day search hit that much harder.
Golden Teeth Closes In, and Mr. Kim Snaps
Back in the present, Golden Teeth spots Min-ji and calls in his thugs to regroup at the office. Big mistake, because Mr. Kim is already there, and he tears through them without mercy. Sang-man finally cracks and comes clean about the whole ordeal, and the moment Kim hears it, he swears he’ll kill everyone involved if his daughter is dead.
In the scramble, Jin-cheol manages to slip away, leaving the other agents behind. Kim, meanwhile, chases down another one of the thugs from the office, catches him, and crashes his car in the process. Golden Teeth gets word of the chaos back at base.
Elsewhere, Han-su pulls Mole Cricket’s body out of the river and runs into Jin-cheol there. The two decide to arm themselves and split up, both heading toward the port, setting up what’s clearly going to be the episode’s final battleground.
The Cold Storage Showdown and the Return of 66
Mr. Kim is en route to the cold storage facility when a group of thugs corners him. At the same time, Golden Teeth tries to cut a deal with Min-ji, pretending he had nothing to do with what happened to her. She doesn’t buy it for a second.
Kim fights his way through the thugs and keeps heading for the cold storage, but he’s suddenly rammed off course by 66’s car. What follows is a brutal, drawn-out fight between the two men, with the new 66 daring Kim to kill him the same way he killed his older brother. It’s personal, it’s raw, and it sets up one of the best sequences of the episode.
Over at the port, Mr. Ju, his men, Han-su, and Jin-cheol are closing in, and the fight between Kim and 66 spills into that same location, with 66 finally starting to piece together the truth about how his brother really died.
The Flashback That Explains Everything: Kim and the Older 66
This is where the episode really earns its stripes. A flashback takes us back to Kim’s training days, when the older 66 and Mr. Kim weren’t enemies at all, they were friends. Close ones. The older 66 remembers Kim’s surname, and asks him not to forget him either.
The next day, the two of them are assigned an operation, dangled with the promise of a house and a reunion with their families if they succeed. During the mission, the older 66 loses his leg and starts bleeding out. Kim tries desperately to save him, but it’s no use. In a gut-punch of a moment, Kim tries to turn the gun on himself, and it’s the dying older 66 who stops him, begging him to survive no matter what. Those are his last words. The flashback closes with Kim being captured by South Korean agents.
I won’t lie, this sequence completely reframed how I saw the “new” 66’s hatred for Kim. It’s not baseless rage, it’s grief built on a lie, and the show handles that reveal with more restraint than I expected.
Min-ji’s Escape and Golden Teeth’s Betrayal
Back in the present, Min-ji is fighting to stay warm and replaying her final moments with her father in her head. Golden Teeth tracks down his own guy, Gang-min, who spills the truth about what happened with Mr. Kim. Min-ji seizes the opportunity to escape, locking Golden Teeth inside the cold storage unit as she goes, a small but satisfying win for her character this episode.
Meanwhile, Kim and 66 are still going at it, with 66 refusing to believe anything Kim tells him about his brother’s death.
Another flashback follows, this time with the South Korean intelligence agency’s boss, right after Kim took down Park Jin-cheol. The boss reveals a bombshell: the leak that compromised Kim’s last operation didn’t come from South Korea at all, it came from Kim’s own North Korean superior, Ru Eung Ryeong. Back in the present, the new 66 is stunned into silence by the revelation.
So Close, So Far: The Chase to the Port
Kim breaks off to go find Min-ji, remembering his late wife’s final words as he finally reaches the cold storage, only to find she’s already gone. Mr. Ju’s men swarm the port, and Min-ji hides in a nearby room, but not, before leaving Kim a message on the floor: an apology.
Kim finds it and immediately goes searching for her, calling out her name. Min-ji hears his voice but assumes it’s a hallucination and doesn’t respond. She jumps the port’s fence, and Kim runs after her. Mr. Ju orders his men to search the area while Mole Cricket, now conscious again, gets caught up on everything that’s happened, including the fact that Jin-cheol has drained his wallet and cards. Han-su, for his part, buys an old motorcycle, while Jin-cheol keeps using the SMD agents’ car to get around.
Sang-min wakes Golden Teeth just in time for Mr. Ju’s men to start torturing him, informing him he’ll be taking the fall for Min-ji’s death. Out on National Highway 87, Min-ji is stuck in the pouring rain, trying to hitch a ride. Golden Teeth, in a last-ditch move, reveals that Min-ji is actually alive and has escaped — sending Ju’s men scrambling to find her and leaving just one man behind to finish him off. Somehow, Golden Teeth survives.
A Gut-Wrenching Cliffhanger
Kim eventually reaches the same stretch of highway where Min-ji had been, spots a CCTV camera, and calls the laundromat owner to try to pin down her location. The other agents, meanwhile, try to talk sense into Mole Cricket about Kim’s increasingly reckless behavior. His plan now is simple and cold: find Min-ji, and hold her hostage if that’s what it takes.
The SMD team mobilizes to track her down. But in a brutal final twist, Min-ji is already in the car, Mr. Ju’s car, as the episode cuts to black.
The Episode Review: Kim’s Closest Call Yet Is Also His Cruelest
If Episode 4 was about Kim gaining momentum, Episode 5 is about that momentum getting violently redirected. This is the “so close, yet so far” episode of the series, and it earns that description in the most frustrating way possible, frustrating in the best sense, because by now the show has fully gotten me invested in Kim actually catching up to his daughter.
The action in this episode is some of the strongest the series has delivered so far. There’s nothing polished or stylized about the way Kim fights, it’s ugly, physical, and desperate, which fits a man who isn’t a trained action hero anymore but a father running purely on adrenaline and fear. Every punch lands with weight, and the choreography never lets you forget that Kim isn’t invincible, just furious.
But the real gut-punch of the episode isn’t the action, it’s the flashback with the older 66. Learning that he and Kim were once friends, bonded by the same dream of freedom and reunion with their families, recontextualizes so much of the tension between Kim and the new 66. It’s not a rivalry born from nothing; it’s grief weaponized by a lie. And that lie traces straight back to Kim’s own North Korean handler, Ru Eung Ryeong, which is a betrayal that lands hard. The people who were supposed to be on Kim’s side turn out to be just as dangerous as the ones hunting him.
I also have to give the show credit for Min-ji this episode. She’s not just a passive victim waiting to be rescued, locking Golden Teeth in that cold storage unit was a genuinely clever, gutsy move. It’s a small moment, but it matters, because it means her survival instincts are catching up to her circumstances.
That ending, though. Kim finding her message and calling out for her, only for Min-ji to write it off as a hallucination, might be the most quietly devastating beat in the whole episode. And having her end up in Mr. Ju’s car right as the SMD team closes in? That’s a gut-punch cliffhanger that raises the stakes considerably. If Mr. Ju decides to bring her in front of his own daughter, Hye-ri, things are about to get a lot darker for everyone involved, including a father-daughter pair on the villain side that could honestly use some serious help of their own.
Episode 5 complicates things in the best way a mid-season episode can. It deepens the emotional stakes, delivers one of the show’s best flashbacks yet, and ends on a cliffhanger that makes the wait for the next episode genuinely painful.
