The Bad Guys: Reign of Chaos 2019

During an inmate transport, several policemen are attacked and killed by assassins, freeing No Sang-sik Jo Young-jin. After recapturing some of the escaping prisoners, Oh Gu-tak [Kim Sang-joong], the former boss of a specialized unit known as the Crime Unit, is called by the head officer to reassemble his team and continue the pursuit. The officer explains that Sang-sik was about to testify to the real leader of the yakuza, and charges Oh with tracking down the remaining fugitives. Oh recruits Woong-Cheol [Don Lee], a former crimefighter now serving time, and Yoo-Sung [Jang Ki-yong], a former police officer, offering them a chance at reduced sentences if they succeed. The duo swiftly secures Kwak No-soon [Kim A-joong], also known as Jessica, whose information becomes a crucial lead in closing in on Kim Chang-min [Park Sang-wook], one of the escaped prisoners. They manage to locate Kim, but Detective Choi [Jeon Ik-ryoung] arrests him, complicating the operation and signaling deeper tensions within the force. It becomes clear that Woong-Cheol is pursuing the mission as part of a personal vendetta to settle the score with the gangster boss who killed his best friend Nam Myung-seok [Kong Jeong-hwan]. After Oh is hospitalized for liver cancer, the unit retrieves Kim and the other prisoners, including Sang-sik, and presses Sang-sik for more details. He reveals that Yoshihara, the gang’s true leader, was behind the operations and that Sang-sik’s diary could expose him. However, the head officer—a mole aligned with Yoshihara—steals the diary and kills Sang-sik, leaving the unit to die in a fire but they manage to escape. Choi helps them pinpoint Yoshihara’s location in a factory, and, with Woong-Cheol’s ally, they assault the basement and defeat Yoshihara’s goons. In a brutal confrontation, Woong-Cheol faces Yoshihara and exacts punishment for Nam Myung-seok’s death, resulting in Yoshihara and his associates being arrested, while the head officer is also brought to justice. Oh recovers from cancer and, inspired by Woong-Cheol’s resolve, returns to duty. The mission ends with the unit’s prison sentences reduced and Woong-Cheol being hired for another assignment, hinting at further clashes to come.
