Plot
Won-ho is a police detective obsessed with taking down Asia's biggest drug cartel, run by a mysterious, unseen kingpin known as "Mr. Lee." Because Lee's identity is a secret, rival dealers frequently pose as him. Won-ho enlists Cha Soo-jeong, a delinquent youth he cares for like a niece, to go undercover. However, she is ambushed and dies in the emergency room, leaving behind a cryptic dying message: an infinity shape (∞).
Days later, Oh Yeon-ok, a cartel executive who recently survived a targeted explosion, attempts to turn herself in. Before she can unmask Mr. Lee, she is poisoned and dies. Investigating the explosion site, Won-ho’s team finds a lone survivor: Rak, a low-level gang member. After Won-ho reveals that Rak’s mother died in the blast and rescues his injured pet dog, a vengeful Rak agrees to cooperate with the police.
Rak arranges a meeting with Jin Ha-rim, a volatile Chinese-Korean drug lord. To ensnare him, the police orchestrate a fake transaction involving a potent new drug called "Laika." Won-ho studies Ha-rim's mannerisms, allowing him to masquerade as the drug lord during a parallel meeting with Park Sun-chang, an ambitious criminal in Lee's network. To protect his cover, Won-ho is forced to snort Laika, triggering intense hallucinations of Soo-jeong before his team stabilizes him.
The sting succeeds, securing raw materials from Ha-rim. Rak takes them to a rural lab where Dong-young and Joo-young, a pair of brilliant deaf-mute siblings, synthesize the drug. Meanwhile, a suspicious new player, Director Brian, arrives at the lab under Won-ho's distant watch. Won-ho’s background check reveals Brian used the same infinity symbol in his past profession, while also uncovering that Rak was adopted into a drug-trafficking family.
Chaos erupts when Ha-rim’s girlfriend, Bo-ryung, kidnaps Won-ho and Rak. In the ensuing shootout, Ha-rim is killed by Rak, Bo-ryung overdoses, and a rigged explosion kills one of Won-ho's officers. Driven by grief, Won-ho targets Brian, convinced he is Mr. Lee after spotting him wearing an infinity-symbol ring. While Won-ho's team raids Brian's base, Rak abducts Brian and reveals that he is the real Mr. Lee. Rak severely burns Brian as retribution for the explosion that killed his mother and injured his dog.
Won-ho finds the mutilated Brian, who is framed by the media as the captured "Mr. Lee." While his superior, Department Head Choi, insists this was a necessary outcome, Won-ho is left unsatisfied with the result of the case. He goes back, only to discover Rak's dog missing. Realizing the dog's true name is Laika—meaning Rak named the drug after his pet—Won-ho uses a hidden GPS tracker to trail Rak to a snowy cabin with the deaf-mute siblings. The two men sit with their guns on the table, and Won-ho asks Rak if he has ever been happy. The camera moves outside as a single gunshot echoes. The extended cut confirms the outcome: a bloody Won-ho leaves the house, revealing Rak was the one shot.

Reception
Critical response
On review aggregator Rotten Tomatoes, the film has an approval rating of 83% based on 18 reviews and an average rating of 5.9/10. Metacritic assigned the film a score of 58 out of 100 based on 5 critics, indicating "mixed or average reviews".
Richard Kuipers of Variety gave a positive review and wrote, "Believer may be more impressive around the edges than at its core, but that doesn't prevent it from delivering a pretty solid two hours of action and suspense that's muscularly directed by Lee and stylishly shot by Kim Tae-kyung. Punching the narrative along is a terrific, predominantly electronic, score by ace composer Dalpalan. All other technical work is spot on."
Cary Darling of the Houston Chronicle rated the film 3.5 out of 5 and said, "Lee Hae-yeong's gripping retelling of Johnnie To's Drug War...stands on its own and is different enough from the original to make it less a clone and more of a genuflection."
Simon Abrams of RogerEbert.com rated the film 2 out of 4 and said, "Believer doesn't add up to much because Lee and Chung essentially tried to improve something that was already perfectly unsettling."
