Read the complete plot breakdown of Yadang: The Snitch (2025), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.
[Lee Kang-soo] profits by providing drug intel to the prosecution, while his partner, ambitious prosecutor Goo Gwan-hee, gains career success from these arrests. Kang-soo was a young man who supported his mother while working as a designated driver. His life changes when he is tricked by a customer into consuming a drug-laced drink and unjustly jailed. Goo recognizes his sharp memory and recruits him to befriend the imprisoned head of a drug trafficking ring, and successfully gathers intelligence on the organization through him. Their partnership flourishes, and Kang-soo becomes a yadang (an informant or undercover operative), while Goo rises through the prosecutorial ranks.
Meanwhile, narcotics officer Oh Sang-jae arrests actress Um Soo-jin for drug use, only to find his investigation undermined by Kang-soo and Goo, who swoop in to seize major busts, including one involving a presidential candidate’s son, Cho Hoon. When Cho’s powerful allies offer Goo advancement, he betrays Kang-soo, crippling him in a staged overdose attack. At the same time, Goo frames Sang-jae and Soo-jin to erase evidence of the drug party and protect Cho. Kang-soo survives, barely escaping with his life, while Sang-jae spends months clearing his name. Eventually, Kang-soo, Sang-jae, and Soo-jin realize they share a common enemy and form a pact for revenge.
The trio targets different figures: Kang-soo aims for Goo, Sang-jae for dealer Yeom Tae-soo, and Soo-jin for Cho Hoon. At first, Kang-soo and Sang-jae successfully subdue Yeom Tae-soo and obtain incriminating evidence, while Soo-jin films a drug party hosted by Cho. However, Detective turns out to be a spy for Goo and tips off Cho. A car crash orchestrated by Cho’s men kills Soo-jin and Kang-soo’s close acquaintance Chang-rak, devastating Kang-soo. Though tempted to give up and leave Korea, Sang-jae convinces him to stay the course.
Goo, seeking to secure Cho’s father’s political future, orchestrates a scheme to fake drug-test results and protect Cho. However, Kang-soo anticipates Goo’s ploy. He secretly records incriminating conversations by swapping Goo’s lighter with a hidden recorder and live-streams them to the public during the presidential debate. Simultaneously, Goo’s hitmen sent to kill Kang-soo are murdered by rival gangs. Goo realizes too late that he has been completely outmaneuvered. Furious, he confronts Kang-soo but is easily defeated. Cho’s father withdraws from the election, Cho spirals into madness and jumped to his death, and Goo is arrested.

Ending Explained – What Happens at the End of Yadang: The Snitch?
Still wondering what the ending of Yadang: The Snitch (2025) really means? Here’s a spoiler-heavy breakdown of the final scene, major twists, and the deeper themes that shape the film’s conclusion.
At the film’s climax, Kang-su devises a clever plan to expose the corruption within the criminal justice system. He secretly records evidence of Prosecutor Ku and Gwan-hee’s illicit activities using a hidden camera, then enlists Kang-su and Sang-jae to ambush their enemies. As they execute their plan, they succeed in capturing and destroying Yeom Tae-su’s drug network and gathering irrefutable evidence of Ku and Gwan-hee’s involvement in corruption. Kang-su then leaks this damning footage online, revealing the extent of the officials’ greed and betrayal to the public. This turns the tide as the truth surface, leading to the arrest of Prosecutor Ku and the suicide of corrupt businessman Cho Hoon, who cannot face the shame. Meanwhile, Gwan-hee’s scheme to manipulate the election is thwarted when the drug test results—falsified by Ku—are exposed, shattering his reputation. The police and media rally behind the truth, and justice is served in a dramatic culmination of the film. Even in defeat, Ku hallucinates cockroaches, symbolizing his addiction to power and greed finally consuming him. The movie ends with Kang-su adopting his old life but with a twist — he secretly records various deals and betrayals, implying he’s still operating as a snitch, but now with a higher purpose. This ending emphasizes that in a corrupt world, truth and corruption are intertwined, and sometimes justice comes from unconventional sources.
