The South Korean film "To Catch a Traitor Detective" is a film directed and written by Kim Hyung-joon, which embodies a magical criminal logic.

Detective Choi Sun-woo carries out a side business, specializing in catching adultery for people and charging high fees. One day, he received a task to catch an adulterer with Jin Xiuzhen, to reach the place where Jin Xiuzhen's husband and other women were fooling around, and to catch the adulterer at the scene. Sounding very exciting, it was not bad, Choi Sun-woo agreed, but unexpectedly provoked a crime. He and Kim So-jin arrive at the hotel and discover that Kim So-jin's husband is next door with another woman. But Kim so-jin doesn't seem to be in a hurry to catch the adulteress, but is mixed up with detective Choi Sun-woo. When Choi Sun-woo woke up, the woman on the bed, Kim So-jin, was already dead, covered in blood, scaring Choi Sun-woo without blood. However, he was a police detective in the end, and when he saw the world, he quickly ran to the next door to see how Jin Xiuzhen's husband was doing. When I looked at it, I learned that Jin Xiuzhen's husband had also died in bed, also covered in blood. When I asked the trembling woman next to me, I knew that the woman was called Jin Xiuzhen, and the man who died in the bed was her husband, so who let Cui Shanyu catch the adultery and die in Cui Shanyu's bed?
Choi Sun-woo did not let Kim so-jin report the crime, but instead summoned his deputy, Choi Qi-feng, and asked him to help hide the body and remove the blood from the crime scene. But in the end, there was no concealment, and Jin Xiuzhen reported the case. As the investigation of the case progressed, Choi Sun-woo thought it would be difficult to hide the sky and cross the sea, but in fact he escaped again and again.
The body was found, Choi Sun-woo thought it was exposed, escaped from the police station, to find the murderer, and really let him find it, because the murderer once tracked Kim So-jin, Kim So-jin called Choi Sun-woo, Choi Sun-woo chased him, did not catch up. Later, he found the murderer and, in the course of the fight, killed the murderer. When Choi Sun-woo finds Kim So-jin, Kim so-jin is about to go away.
When the police arrive, Choi Sun-woo confesses the murderer's motives, and the case is solved. Choi Sun-woo went to the inspection department again and asked the inspectors to destroy the fingerprints he left on the corpse, leaving no trace. In the end, Choi Sun-woo understands that Kim So-jin was forced by her husband to watch him with another woman, and that other woman wants Choi Sun-woo to catch a woman who claims to be Kim So-jin, and the real Kim So-jin has already started to kill, hiring a killer to kill the woman and her husband, and asking Choi Sun-woo to wash the floor.
Jin Xiuzhen had already clearly felt Choi Sun-woo's temper, and it was just to calculate him to pull him in. While Choi Sun-woo is busy exonerating herself and tracking down the real culprit, Kim so-jin has gone away with her husband's large inheritance.
The case is closed, the direct murderer is dead, Choi Sun-woo, who is responsible for burying the body, is not guilty, and Jin Xiuzhen, who sets up the situation behind the scenes and dominates the development of the case, is the one who uses the magical criminal logic. When Choi Sun-woo receives a ticket from Kim So-jin asking him to go abroad to meet him, Choi Sun-woo still cares about his wife at the police station and throws away the ticket.
The magic logic of crime makes the master behind hiring the murderer a big winner in life, and the detective Choi Sun-woo is just the one being played. The film has some dramatic color, of course, it is not very real, but it is enough to illustrate the awakening of women, which is quite feminist, and also makes people think deeply after watching it. After the addition of elements such as cheating, catching adultery, killing people, burying corpses, selling stolen goods, fighting, etc., the film has a certain degree of watchability, and it is also full of certain comedic elements, which can make up for the loopholes in the plot, especially the magical criminal logic makes many people see what is going on at the end, which is much more open than domestic films...
