The prestigious international sporting event, World Sports Games (WSG), held every four years, is going to be hosted in Tokyo. The media are also focusing their attention on the HyperLinear train that can reach 1,000 km/h and launch of its service on the opening day of the WSG. However multiple incidents occur in which top executives of WSGs sponsor companies are kidnapped but then are immediately released. No one seems to know who might be behind these incidents, but similar occurrences were observed during the WSG inauguration in US 15 years ago. When Conan learns of Alan McKenzie, former chief of FBI and now the head of WSG committee, is to get on the first run of the bullet train, he and Shuichi Akai make their move. Meanwhile, Akais sister Masumi Sera and his mother Mary are also in pursuit of the same case and have boarded the train. To make matters even more curious, Akais younger brother and professional Shogi player Shukichi Haneda too happens to be visiting Nagoya, where the train is scheduled to begin its run!
