kyung-Gu Sol stars as Detective Kang, a rough around the edges anti-hero who strives on walking close to the edge, and often crosses the line with falsifying evidence, taunting his suspects in a similar way to Dirty Harry and beating confessions out of the criminals he apprehends. To make matters worse, after his partner commits suicide, internal affairs are on his case for taking bribes putting his career in jeopardy.
Meanwhile, Gyu-Hwan Chul is a devoted father, loving husband and all round family man with an honest persona but when his delicate sensibilities get bruised his esoteric, sociopathic ego quickly emerges to enact before disappearing in the blink of an eye. The first part of this movie slowly introduces both characters separately, allowing the viewer to understand both protagonists, but their paths finally cross one rainy evening intensifying the momentum exponentially.
Detective Kang is investigating the murder of an elderly couple and instantly knows that the filthy rich Gyu-Hwan Chul is the prime suspect but he has no evidence or clear motive to bring the remorseless killer to justice. To make matters worse for the Detective is the fact that Gyu-Kwan Chul is very intelligent and immensely proficient at covering his tracks, the complete polar opposite to Detective Kang in both appearance and demeanour.
This paves the way for an excellent game of cat and mouse with some brutal entertainment (Kang packs a mean punch in one on one combat) that also manages to create a huge amount of humour along the way thanks to the electric performance by kyung-Gu Sol, as Detective Kang, with his hilarious taunting dialogue. The hero versus the villain doesn't come much better than this one, an unmissable flick for fans of Korean cinema.
