3 victims. 4 suspects. 4 detectives. 1 deadly secret.
About
Four detectives arrive at an elite private school in one of Seoul’s wealthiest districts after three students become connected to a shocking case: two are missing, while one is found dead. Three detectives have transferred from the same precinct, while the fourth comes from another. Each brings a unique ability—the brilliant female detective has an IQ above 160 and an extraordinary photographic memory; a male detective remembers everything he hears and notices tiny details others overlook; a female detective specializes in profiling and understanding behavior; and the final detective has exceptional intuition, recognizing when someone’s behavior suggests they are hiding the truth. The victims come from very different backgrounds. One is the daughter of a powerful pharmaceutical CEO. Another is a male scholarship student who had been investigating the secrets of a wealthy businessman involved in illegal activities. The third, a girl and daughter of an electrical-company CEO, is found dead. The three had secretly been working to expose the businessman. Four suspects quickly emerge: a wealthy, arrogant female student whose father is Seoul’s mayor; a male student closely connected to the missing scholarship student; a teacher who has secretly had inappropriate relationships with numerous students; and the businessman himself. At a school where wealth, influence, and reputation control everything, the detectives must uncover who is lying—and what the three students discovered before one of them was killed.
