Meitantei Conan: Tenkuu no Lost Ship

The latest Suzuki corp. challenge to Kaitou Kid turns deadly as the dirigible meant to be the stage to trap Kid becomes a floating fortress as mercenaries from a terrorist group hijacks the ship with everyone still on board. Even worse is that this group has possession of a recently stolen bioweapon and appears to be planning to use it against the population of an entire city by releasing it in the sky as the dirigible passes by. Conan, Kaitou Kid, and Hattori must uncover enough of their nefarious plot before time runs out and find out if there is something far more sinister to their plot than just what they allowed the world to know about.
