Detective Ma Seok-do, Don Lee, and his team are promoted to the Metropolitan Investigation Unit, plunging into a high-stakes case that opens with the mysterious death of a woman named Go Sun-hee. The investigation quickly pivots on the autopsy, which reveals Sun-hee had been using a dangerous drug called Hiper, hinting at a larger network of narcotics rather than a simple homicide. The team dives into the city’s nightlife and criminal underworld, tracing the drug’s origins and the people who move it.
In a tense nightclub interrogation, they confront the club’s powerful circle and uncover a link to a yakuza figure named Hiroshi, whom Kang Yoon plays. The confrontation lays bare a supply chain that runs from Incheon into the city’s most guarded venues. Ma Seok-do’s squad manages to seize 20 kilos of Hiper and detain Hiroshi, but the moment is undercut when a crooked cop, Joo Sung-chul, betrays them, kills Hiroshi, and makes off with the drugs. The ambush is brutal, yet the team survives, underscoring how dangerous the corruption they face truly is.
As the pieces start to fit, it becomes clear that Joo Sung-chul is not acting alone. He is protecting a ruthless syndicate known as the White Shark Clan and has quietly turned the pursuit into a profit-driven nightmare. The White Shark’s appetite for Hiper forces them to hire a ruthless hitman named Ricky to recover what was taken and to get ahead of the police. The pursuit grows more personal as Ma Seok-do learns of another supplier named Tomo, which pulls the detective deeper into a dangerous drug war between Ricky and Joo Sung-chul. The chase leads to a yacht, where a clue brings the investigators to a shocking discovery about the drug’s reach and the people willing to do anything to cash in.
A tense twist of negotiations unfolds aboard the watercraft, where an uneasy deal is struck with Joo Sung-chul—a plan that involves Chorong, Ko Kyu-phil stepping into the fray as an important ally. Yet the alliance is unstable, and Joo Sung-chul abruptly shifts gears, aligning with Ricky to reclaim the Hiper stash. Ma Seok-do finds himself captured and interrogated by Ricky, who believes breaking his enemy will sear a path to the truth. The detective endures harsh questioning, but he fights back, ultimately turning the tables on Ricky and turning the tide of the confrontation.
With a tracker hidden in a stolen bag, Ma Seok-do traces the final moves to Joo Sung-chul’s office, where a decisive police operation seals the fate of the White Shark Clan and their illicit empire. The arrest of Joo Sung-chul and the takedown of the syndicate bring a hard-won sense of closure to the case, and Ma Seok-do and his teammates share a restrained victory, knowing the city’s drug problem runs deeper than a single bust.
In the mid-credits sting, Ma Seok-do tracks down Jang I-soo for a new lead, signaling the start of another investigation and setting the stage for the film’s sequel. Park Ji-hwan appears as Jang I-soo in this pivotal moment, underscoring how one case often spirals into another, leaving the door open for what comes next in the ongoing pursuit of justice. The story weaves together multiple threads—police procedure, corruption, rival crime factions, and the personal resolve of a detective who refuses to quit—crafting a tense, atmospheric thriller that keeps the tension high from start to finish.
Throughout, the characters’ fates are shaped by a web of loyalties and betrayals, and the film preserves a steady, neutral tone that favors clear, straightforward storytelling over sensationalism. The action scenes are tightly choreographed, the investigations are methodical, and the atmosphere leans into the gritty realism of on-the-ground policing. The film closes on a note of cautious triumph: a drug war disrupted, a criminal network dismantled, and a seasoned detective who has earned a moment of hard-won validation, even as the next chapter looms on the horizon.
