One day, Maori Kogoro received an invitation, which was a request from a mysterious man, and he needed to go to an amusement park in Yokohama. Kogoro and Conan happily arrived at the amusement park, and also wore watches that allowed them to enter and exit the amusement park without any obstacles, representing VIP status. Unexpectedly, they fell into the trap of the mysterious man. All those who wore watches were not allowed to leave the amusement park, otherwise there would be an explosion. From now until 10 o'clock in the evening, if Conan and Kogoro could not solve the mystery, Ran and the Junior Detective Team would also be shattered along with the amusement park. However, what was even more unexpected was that the man actually called Conan directly Kudo Shinichi.
