The Detective Boys sneak into an abandoned building that due to be demolished to play hide and seek. While playing Genta hears someone tapping a 2-5-2 code which is used in Japan to call for help. They find two construction workers who claim to be surveying the area before destroying the building by implosion. Conan quickly deduces they are confining a person in the building due to regulations preventing the building they are in to be imploded. The criminals, realizing they have been figured out, seal up the building and chase after the kids. Conan is knocked out by his rebounding soccer ball and Ai is captured. The criminals prevent the remaining Detective Boys from calling the police by threatening to kill Conan and Ai.
