Episode 8 of "Trigger" resumes where the intense police operation to apprehend Jung-man left off, intertwining with Jung-man's cunning counter-maneuver to seize control of Seok-ho's empire. As Mr. Kim steps into the club to confront Seok-ho, the police storm in right behind him, setting the stage for chaos.
Meanwhile, in the steamy confines of the bathhouse, Jung-man's ruthless men dish out a grim fate to Seok-ho's loyal followers. Simultaneously, within the club's confines, a dramatic confrontation unfolds between Mr. Kim and Seok-ho, culminating in their mutual demise. Seizing the opportunity, Jung-man leads his henchmen to Seok-ho's stash house, amassing all the wealth while being fully aware of Seok-ho's betrayal to the authorities.
Elsewhere, Lee Do receives intel indicating Jung-man's absence at the club, only to witness Jung-man triumphantly returning to their hideout with his cronies. Jung-man ascends the stairs with the ill-gotten gains, greeted by the ecstatic crew who believe their elaborate plan has triumphed.
However, their euphoria is swiftly shattered by Lee Do's strategically timed raid. As Jung-man attempts to flee, Lee Do unleashes his sharpshooting prowess, disabling his vehicle and neutralizing Jung-man. The police swiftly take Jung-man and his men into custody, confiscating an arsenal of firearms.
The police's triumphant seizure of Jung-man's weapons not only deals a heavy blow to his criminal enterprise but also bolsters their public image, hailed as heroes in the fight against gun trafficking. Moon-baek, disheartened by the turn of events, stands in stark contrast to Jack's raging fury.
The cache of seized firearms prompts an inevitable investigation, raising the specter of CIA involvement. Such scrutiny poses a grave threat to their ongoing operations. Jack, recognizing the impending peril, issues a stark command to Moon-baek: wrap up their activities in South Korea and retreat back home, before their meticulously crafted plans unravel completely.
In a startling twist, Hyun-sik's daughter tragically ended her own life, ensnared by a deceptive scheme that decimated her finances, including the money she had borrowed from her father's pension. Elsewhere, the National Security Council received additional intelligence from the CIA about the shadowy organization behind the illegal gun trade. The International Rifle Union, a prominent player in the black market, is deeply involved in the sale and distribution of firearms. Backed by influential politicians and global corporations, this organization wields considerable power. The individual responsible for overseeing weapons distribution in South Korea is none other than Blue-Brown, alias Moon-baek.
Meanwhile, Moon-baek overhears the nurses relentlessly harassing one of their own, a young woman who had been working nonstop for a week without a break. When she requested to go home to change her clothes, the nurses callously instructed her to wash the ones she was wearing and return to her post immediately.
Later, Moon-baek meets with Reporter Wang and offers him a substantial sum of money to capture footage of individuals using his guns. He intends to exploit these videos, tapping into people's fears and emotions, thereby igniting a desire for gun ownership among every Korean citizen.
Unbeknownst to Moon-baek, Lee Do discovers that the distributed guns contain tracking devices. He takes the device to his military friend, who reveals its capability for wiretapping. However, the device alone cannot intercept conversations; it requires an auxiliary device to function. Lee Do returns to the station and meticulously searches through all the guns for the auxiliary device but only finds the GPS. He then receives a call from Detective Seo, who informs him that another common denominator among the gun owners is that their phones had been hacked.
Lee Do arrives at the NSU for a briefing and learns that whenever the IRU intends to expand into a new territory, they leave bullets as a sign of their intent. In this case, the first victim did not commit suicide but was murdered by Moon-baek. Moon-baek was trafficked as a child by the same individual, and the NSU suspects that he has returned to seek revenge on the country that deserted him.
At the very heart of their joint investigation, Lee Do unexpectedly receives a call from Moon-baek, who has infiltrated the system using a firearm surreptitiously introduced by a rogue employee. With a sense of urgency, Moon-baek reveals to Lee Do a dire situation: another citizen is poised to wield a gun. Through the hacking, Moon-baek presents a chilling footage—Hyun-sik, emerging from his vehicle armed, and striding purposefully towards a club. In a daring challenge, Moon-baek dares Lee Do to intervene and save Hyun-sik from his impending actions.
As Lee Do sprints to Hyun-sik's location, the investigative team concurrently works tirelessly to decipher the chip embedded in the guns, aiming to pinpoint Moon-baek's whereabouts. Meanwhile, Hyun-sik, consumed by vengeance, unleashes his fury upon those he believes are responsible for duping his daughter. Lee Do, with every fiber of his being, races against time to reach Hyun-sik and halt his descent into chaos.
Concurrently, the other detectives trail the GPS coordinates, their eyes set on apprehending Moon-baek. Yet, their meticulously laid plans are foiled as Moon-baek, ever the step ahead, has anticipated this very maneuver.
