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.

On a dark night, the Japanese police is raided by a spy. Different countries' intelligence agencies—such as England's MI6, Germany's BND, and America's CIA—as well as the FBI's secret files are going to be taken, but public safety officers lead by Tooru Amuro arrive just in time. The spy steals a car and escapes. The spy and Amuro are then locked in a dead heat on the highway, and just as it is about to cause an accident with multiple cars, the spy's car is hit by FBI agent Shuichi Akai's rifle bullet and falls of the roadway.
The next day, Conan and his friends go to a newly-remodeled aquarium in Tokyo. Under the main attraction, a Ferris wheel, Conan finds an attractive woman alone and injured. Her left and right eyes are different colors.

But the woman is in a state of amnesia where she doesn't even remember her own name, and the cellphone she's carrying is broken. Conan and his friends promise to help her regain her memory, so they stay with her.

Throughout all this, Vermouth is watching behind the scenes. Afterwards, she pulls out a silencer and speaks into an attached intercom, "It's as planned, Gin."

Long ago, the blacksmith Adin forged a belt of seven powerful gems, one from each of the seven tribes of Deltora. Wielding the belt's unparalleled power, he repelled the Shadow Lord's attempt to overthrow the kingdom. Adin was crowned king of Deltora, but he never forgot that the enemy remained unbeaten. Centuries later, memory of the Shadow Lord has become faded and almost forgotten, and the people of Deltora see their monarchy as detached and uncaring. Much to their dismay, the Shadow Lord strikes once more, breaking the Belt of Deltora by scattering the seven gems across the continent. Jarred, a close friend of the young king Endon, assists him and his wife in escaping from the castle as the Shadow Lord takes over, and they part ways to go into hiding. The Shadow Lord now reigns over Deltora and many years pass under his tyrannical rule. However, there is a glimmer of hope in Jarred's son Lief, whom he has lovingly raised and trained to find the scattered gemstones and reassemble the Belt of Deltora. Along with his companions Barda and Jasmine, Lief must face devious enemies and dangerous beasts to oust the Shadow Lord and return peace to Deltora.
