The Policeman's Lineage (2022) Ending Explained – Final Scene & Meaning

In the end, we see that Choi, having uncovered the corruption rooted deep within the police and linked to his own family’s dark past, chooses to manipulate the system rather than completely break free from it. After confronting Park and realizing he had been misled by the evidence and Park’s actions, Choi finds himself entangled in the cycle of corruption and morality. Despite Park’s arrest for murder, Choi manages to leverage his understanding of the widespread nepotism and illicit ties to secure a deal with the powerful Yeonnam group. He threatens to expose their involvement in the police's illegal activities unless they allow him to meet with their top boss, which he does, using his father’s old connections. Through this meeting, Choi extracts promises that will keep him ahead in a corrupt world—he demands and receives immunity for himself and Park, along with access to sensitive information that implicates high-ranking officials and influential figures involved in criminal activities. By this, he aligns himself with the corrupt system for what he perceives as the greater good, aware that in a deeply compromised environment, a certain level of dishonesty and manipulation is necessary. The film concludes with Choi fully embracing his new moral code, understanding that in the world of police and power, righteousness is often a complicated, and sometimes costly, negotiation. His journey ends with the acknowledgment that the lineage of police work is intertwined with corruption, and sometimes survival depends on playing by these shadow rules.
