For several days, pairs of unidentified foreigners have been turning up dead. While discussing the case on their way home from school, Conan, Genta, Mitsuhiko, Ayumi, and Haibara come across a foreigner who has fallen off a building. When Conan sees Vodka on the roof, he instructs Haibara to take the three kids and leave the scene. Conan discovers an FBI ID and phone displaying a coded message on the fallen foreigner and heads to the Kudo family home, where he finds a gathering of FBI agents.
