Conan and his friends get caught up in a mysterious murder case, all involving the murderer leaving a broken tea cup behind. Pushing the case aside, they go to an elite party at the 67th floor of an enourmous building, when the murder happens again. This all pales in comparison when suddenly 2 of the building\'s stories explode. Gin and Vodka, the same ones who shrunk Shinichi to Conan, are intent on killing Ai, who they still think is grown up and at the party. With a burning building around them, and bombs in every room, ready to explode, Conan has to push through the crisis before the building gives in.
