A murder committed by a genius that is solved by another genius. The film showed us not only a story of "how to get away from the killer" and "you can never get away with murder," but also demonstrated that self-sacrifice can be great, the sacrifice of others is definitely unacceptable.
As the film opens, we know a genius of mathematics who teaches at a high school. In a parallel story, a read morebody is found of a 40-year-old guy. Jianbei police enter the case and quickly reduce the list of suspects, including the ex-wife of the murdered homicide. By chance, the neighbor's ex-wife is an acquaintance of the police officer responsible for the case ...
The film is a remake of the Japanese film based on the Japanese book of the same name, this time transposed into a Chinese setting. (I read the book, very good).
Already the film is lousy, very ill adapted of low production with incredibly strange performances. The soundtrack at some moments seems more like we hear a radio, the music increases when the "drama" rises, only to disappear to a black screen, as if we were going to a TV or radio commercial. In addition, the film changes genre and format in the middle of the film, as what happened to the murdered face is revealed halfway.
