It is a sequel to the 2018 film Believer and stars Cho Jin-woong, Cha Seung-won, Han Hyo-joo, Oh Seung-hoon, Kim Dong-young, and Lee Joo-young.

[1] The sequel follows Won-ho's investigation of looking for "Rak," who disappeared after Brian's incarceration, while getting to the core of the elusive drug cartel.

The film is directed by Baek Jong-yul and the cast includes the return of lead actors and actresses Cho Jin-woong and Cha Seung-won, Han Hyo-joo, Oh Seung-hoon, Kim Dong-young and Lee Joo-young.

[3][12] James Marsh of South China Morning Post rated the film 1/5 and criticized the "excessive violence in a Korean action movie" and character of Han Hyo-joo writing, "preposterous new villain, Seob So-chen, aka Big Knife, a deadpan, chain-smoking angel of death who descends onto the scene from China sporting bad skin, even worse teeth, thick glasses and a penchant for decapitations."

He concluded, "Even those who remain committed are in for two exhausting hours of relentlessly histrionic mayhem and misdirection that ultimately adds nothing but questions to its infinitely superior forerunner".
