The group causes the explosion of a high-security lab storing a virus—said to have a mortality rate of 80% with no known cure. This act of terror dominates the headlines, overshadowing the unveiling of the world's biggest airship developed under Jirokichi Suzuki.

Conan Edogawa is permitted to board the airship along with Kogorou Mouri, Ran Mouri, Sonoko Suzuki, Professor Agasa, and the Detective Boys.

Soon after, symptoms begin to appear among the passengers and chaos ensues. Seizing the opportunity, the Red Siamese Cats suddenly appear and hijack the airship! To stop the assailants, Conan and Kaitou Kid, along with their allies, must work together to decipher the clues and discover the Red Siamese Cats' real objective before time runs out.
