A police procedural thriller, crammed with stock characters and situations, not to mention overly caricatured underworld types, brought alive by vivid and engaging direction. Investigating two identical (but seemingly random) murders on the night streets of Seoul, the cops round up the usual suspects and start twisting arms. They end up with four identikit portraits - and the problem that the sketches look like pretty much any group of young Korean men. But the antithetical impulses of the impulsive cop Bang (rapper Yang, definitively establishing himself as a movie actor) and his more measured colleague Oh (Jeong) finally get results and an intermittently exciting manhunt ensues. Above average.
