Jung-min is the new detective assigned to a neighborhood where a serial killer commits murder every rainy Thursday. Laidback and blundering at his job, Jung-min is actually secretly studying for a civil servant exam to get away from his boss who's always picking on him. Every day, residents protest outside the police station, shouting that the police should make up for the falling apartment prices and catch the murderer. To make matters worse, Jung-min's mother who happens to be the president of the women's association is leading the protest. He vows to catch the killer this time in order to save his dignity as a detective and a son. However, his elaborate plans are upset by the appearance of Young-seok, the neighborhood unemployed bum. Because of the reward for the killer's capture, Young-seok is trying to catch him well, and his natural detective skills lead him to always arrive at the crime scene one step ahead of the police. Furthermore, he criticizes every little thing that Jung-min does and is a royal pain in the neck. Jung-min absolutely cannot let Young-seok solve the case and take away his chance of a lifetime, so a rivalry forms between the two as they both race to catch the killer.
