Professor Park (Kim Kang-woo) is tired of his CEO wife Yoon (Kim Hie-ae), especially after he falls in love with one of his students. He devises a way to kill Yoon and get away with it: an untraceable (and extremely fatal) poison only ever developed in his chemical lab will be the means, and making her body vanish from the forensic morgue will be his salvation because, after all, no body, no murder, right? He feels completely safe when he discovers that the police investigating the case include a newbie, a by-the-book square and a kid only interested in his Instragram feed, all led by Jung-sik (Kim Sang-kyong) a once-brilliant but now sozzled detective. Only none of what Park sees happening is what it seems....It's difficult to describe the number of layers to this murder mystery, and I wouldn't want to say anything more about the plot because that would spoil the charm of the film. South Korea has a fantastic film industry, full of extremely talented people in all aspects from acting to directing to writing to creating strangely spooky forensic labs; this particular story is a remake of a Spanish film from 2012, "The Body," but it's a thoroughly Korean film by the end. A joy to behold - but don't take your eyes off the screen or you might miss yet another twist of the tale!
