The Kid and Conan dynamic shifts the entire formula, you're not watching a detective solve a case, you're watching two masters play separate games on the same board. An airship hijacking trades the usual small-town mystery for genuine dread, and the tension holds because the terrorist threat is real in ways Conan's usual cases aren't. The mystery itself is transparent enough that you stop trying to solve it and start watching how two brilliant thieves handle a situation that wants them dead.
Conan boards the world's largest airship, built under Jirokichi Suzuki, along with Kogoro, Ran, Sonoko, Professor Agasa and the Detective Boys. The unveiling comes with a challenge to Kaito Kid, the phantom thief, to steal the Lady Sky jewel on display. The trip turns to chaos when a caller claims a deadly virus has been released on board and passengers begin showing symptoms. A terrorist group called the Red Siamese Cats then hijacks the vessel. Conan and Kid must work together with their allies to read the clues and uncover what the terrorists are really after before time runs out.
