One night, the Tokyo National Institute of Microorganisms is attacked by a mysterious organization calling themselves the "Red Siamese Cats." 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. Peculiarly, the unveiling has a note attached for Kaito "Kaitou Kid" Kuroba, challenging him to steal the jewel on display—the illustrious Lady Sky.

Conan Edogawa is permitted to board the airship along with Kogorou Mouri, Ran Mouri, Sonoko Suzuki, Professor Agasa, and the Detective Boys. However, their fun comes to a halt when an unknown caller contacts Jirokichi and declares that they have released a certain virus in the smoking room. 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.

Animated Flash shorts based on the light novel series "Haiyore! Nyaruko-san." In these shorts, Nyarlko, an anthropomorphized female version of Nyarlathotep from the Cthulhu Mythos, is constantly being told off by Mahiro, a normal human boy, for all the crazy or stupid things she does. In one of the shorts, Nyarlko is drawing a cover design for a body pillow. It turns out that the pillow's subject is a half-dressed Mahiro in what appears to be a hot and heavy scene with Nyarlko. Naturally, Mahiro proceeds to stab Nyarlko in the hand with a fork and threatens to kill her if she releases the pillow design. Other shorts revolve around various gags and occasionally feature Cthuko, an anthropomorphized female version of Cthugha, who's madly in love with Nyarlko.
