The fight against the corrupt assemblyman comes to a head, with the stakes inching ever higher. In the face of temptation, our protagonist must choose between reverting to his self-serving ways or upholding the pursuit of justice.
EPISODE 4 RECAPA humiliated and guilt-ridden Soo-yeol is washing his face in the washroom when he receives a call. It's Kyung-tae calling from a payphone — he's regained consciousness, but he's being chased.
We rewind to two hours before In-bum's death. Standing over an unconscious Kyung-tae, In-bum had filled a syringe with a suspicious liquid. As In-bum draws near to inject it into the IV drip, Kyung-tae's fist clenches slightly. He's awake, but he can't show it.
Luckily, he's saved in the nick of time by the police officers who have returned from their break. In-bum takes his frustration out on them, and by the time he turns around, Kyung-tae has disappeared. In-bum notices the open window and rushes out of the room, only for the cabinet door to creak open after he's gone. Smart cookie Kyung-tae had hidden inside.
After searching the surroundings to no avail, In-bum gets into his car to give chase, only for Kyung-tae to accost him from the backseat. Holding a scalpel to In-bum's neck, Kyung-tae demands to know if he killed Yoo-na.
In-bum denies it, then reveals that the murderer is Assemblyman Do. Kyung-tae doesn't believe him, so In-bum retrieves a duffel bag from his gym and hands over a voice recorder to Kyung-tae. In-bum had recorded Assemblyman Do's assault on him.
When In-bum scoffs that someone like Kyung-tae won't be able to take Assemblyman Do down, a determined Kyung-tae counters that he will, then escapes from the car with the duffel bag.
Back in the present, Kyung-tae tells Soo-yeol that he knows who killed Yoo-na, and entreats him to help catch the culprit.
Before Soo-yeol can leave the washroom, Assemblyman Do comes sauntering in. He dismisses Soo-yeol, who insists that he'll wait to see him off. With a smarmy chuckle, Assemblyman Do reminds Soo-yeol that Kyung-tae's waiting for him, isn't he? Oh no...
Later, Assemblyman Do gets into the drug dealers' car. They inform him that they've taken care of In-bum and recorded the deed on a phone. However, they went through In-bum's dashcam footage and saw him handing over the voice recorder to Kyung-tae. Incensed, Assemblyman Do orders them to bring Kyung-tae to him.
Hee-gyeom seeks Gye-shik out to ask him about the deceased Min-soo. Informing him that Min-soo had been pursuing Assemblyman Do, Hee-gyeom theorizes that Shim Sang-ho, the drug dealer that killed Min-soo, may have done so under the assemblyman's orders.
Meanwhile, Soo-yeol meets up with Kyung-tae in an empty, deserted office. In a resigned tone, Soo-yeol tells Kyung-tae that there's nothing they can do without evidence or witnesses. Kyung-tae offers In-bum's recording, but Soo-yeol's quick to shut it down. Nowhere in the recording does Assemblyman Do explicitly admit that he murdered Yoo-na. With everything being circumstantial, they have no proof, especially now that In-bum is dead.
Chastened, Kyung-tae apologizes for troubling Soo-yeol, then thanks him for helping him — Soo-yeol was the only person he could think of. Soo-yeol exasperatedly reminds Kyung-tae that he's being framed for murder; he ought to be worrying about himself, not others. Kyung-tae apologizes again, and Soo-yeol sighs that the powerless have no choice but to apologize and kneel.
Outside, Soo-yeol recalls how he sacrificed his dignity to grovel in front of Assemblyman Do. Grimly, he makes a call to the assemblyman.
Before long, Assemblyman Do's hired drug dealers are entering Soo-yeol's old office. Kyung-tae awakens to a whole gang of men, who step aside to let Assemblyman Do through. Following behind is a morose Soo-yeol, who can't meet Kyung-tae's betrayed gaze.
