The episode starts with Conan Edogawa, the main protagonist, and his friends Ran Mori and Shinichi Kudo (who is secretly Conan) visiting a local amusement park. The park is hosting a special event, and the group decides to spend the day there. However, their fun is short-lived, as they soon become entangled in a mysterious case.
As Conan digs deeper, he discovers that Mr. Kuroba was involved in several shady business deals and had many enemies. The list of suspects grows, and Conan must use his analytical mind to piece together the evidence.
The episode introduces several suspects, each with their own motives and secrets. There’s Mr. Kuroba’s business partner, who stands to gain a significant amount from his death; a former employee who was fired by Mr. Kuroba; and a mysterious woman who was seen arguing with the victim earlier that day.
