Gangnam B-Side: Season 1, Episode 3 - Episode 3 (2024)

At the start of the episode, police discover Gang-su's body, and the investigation immediately centers on the blade found at the scene, which is identified as belonging to Gil-ho. Prosecutor Min is told the weapon links Gil-ho to the murder, but the timing does not fit a simple frame-up because she had already seen Gil-ho jump off the bridge, making it unlikely he was physically present when Gang-su was killed.

The story then moves into the earlier relationship between Gil-ho, Jae-hee, Jung-hwa, and Madam Baek. Gil-ho originally worked as a chaperone for Baek, and Baek later encountered Jae-hee and Jung-hwa and brought them into her "family" after seeing that they needed shelter and support. Baek promised them she would not force them into anything, even though the work around her organization was not what they had hoped for.

A little later, Gil-ho and Jae-hee find Madam Baek dead. Her body has a stab wound, and drugs are found beside her, turning the scene into a suspicious death tied to the darker parts of the operation rather than an open, straightforward murder.

Back in the present, Dong-woo catches Ju-yun doing illegal business while he is still trying to track down another man connected to Gil-ho. This encounter reinforces that multiple people around the case are operating illegally, and Dong-woo continues pressing forward with his own search rather than backing off.

At the same time, Seo-jin spots Jae-hee at a subway station. Before Seo-jin can properly reach her, Jae-hee runs away after hearing the name of her friend while Seo-jin is on the phone, and the moment slips away before any direct conversation can happen.

Elsewhere, Prosecutor Tak, Min's boss, makes clear that he is prepared to do whatever it takes to derail the investigation. The plan is to frame Gil-ho and shut the case down instead of allowing it to expose the larger network behind the disappearances and murders.

Gil-ho then receives a message from Noh saying that Noh has found Jae-hee. Noh orders him to come to the club Hyena at midnight and warns that if Gil-ho is even slightly late, Jae-hee will be killed, forcing Gil-ho into a desperate race against time.

The episode then ends on a new shock: Noh is found dead in his room. The death is presented as a suicide, but the circumstances strongly suggest it has been staged by more powerful people in the background. At the same time, it is revealed that Dong-woo's daughter Ye-seo has been kidnapped by a woman, adding another crisis on top of the main case.

Gil-ho's search in episode 3 takes him to a harder truth, and Dong-woo's investigation pulls him deeper into Gangnam's hidden network. By the end, the case is no longer just about one missing person, and the people involved are forced into a tighter, more dangerous circle.

In episode 3, Gil-ho keeps looking for Jae-hee, but the information he finds does not bring him closer to a happy reunion. Dong-woo follows the trail using the evidence Gil-ho left behind, and his investigation leads him into Gangnam's criminal connections. Seo-jin's side of the case also turns darker, and she calls Dong-woo as the pressure on the investigation increases. The ending leaves Gil-ho facing unsettling news, while Dong-woo is pushed further into the center of the case.

What follows is the ending as a straight narrative:

Gil-ho continues his search through Gangnam, moving from clue to clue with the hope that Jae-hee is still reachable.
The trail does not stay simple for long.
Instead of a clean answer, he is met with information that changes the shape of the case and makes the situation feel more dangerous and more tangled.

At the same time, Dong-woo uses the key evidence Gil-ho left behind and works the Gangnam angle of the investigation.
That evidence leads him to an unexpected encounter, and the story pushes him closer to the people and places hiding behind the city's polished surface.
His role in the episode becomes less about observing the case and more about being drawn into it physically and personally.

Seo-jin's investigation also reaches a point where it turns dark enough that she has to contact Dong-woo directly.
That call signals that the case is no longer contained, and the people working it are now relying on each other more openly.
The episode ends with Gil-ho still searching, Dong-woo deeper in Gangnam, and Seo-jin confronting a worsening situation.

The fate of the main characters at the end of episode 3 is this:

• Yoon Gil-ho is left with unsettling news and continues forward without closure.
• Kang Dong-woo is pulled deeper into Gangnam's criminal side through the evidence trail.
• Min Seo-jin is forced to widen the investigation and call Dong-woo as the case darkens.
• Jae-hee remains missing, with no safe resolution in the episode's ending.

If you want, I can also give you the ending of episode 4 in the same style.

No post-credit scene is mentioned in the available episode 3 coverage, and the episode 3 recap/reviews describe the story ending without any after-credits tag or bonus scene.

The episode's ending material instead focuses on the main plot developments: the police finding Gang-su's body, the weapon being traced to Gil-ho, and the investigation escalating around the murder and the larger criminal network.

If you want, I can also give you a full scene-by-scene summary of Episode 3's ending so you can see exactly where the credits roll.

No, this is not family friendly. Based on the series' crime-thriller genre and the parental guidance reports, Episode 3 can be expected to include material that may be upsetting for children or sensitive viewers.

Potentially objectionable or upsetting elements may include: - Violence and gore; the show is rated severe for violence/gore overall. - Strong profanity; the overall parental guide rates profanity as severe. - Alcohol, drugs, and smoking; the parental guide rates this content as severe. - Intense or frightening scenes connected to the investigation and dark criminal setting. - Sexualized bar imagery / partial nudity; the parental guide notes half-naked males and females dancing in a bar. - Dark themes involving crime, corruption, and missing persons, which may be emotionally disturbing even when not explicitly graphic.

For Episode 3 specifically, the available episode descriptions only say that Dongwoo investigates in Gangnam with crucial evidence and has an unexpected encounter, while the investigation "takes a dark turn." That is enough to indicate a tense, adult-oriented episode, but not enough to detail every scene without risking spoilers.

If you want, I can also give a very brief spoiler-free content warning tailored for: - young children - teens - trauma-sensitive viewers
