The movie starts with Ran and Conan (using Shinichi's voice) talking over the phone about the bomb explosion at a musical facility; and they eventually get into an argument. Ran, Kogorou, Conan and his friends have been invited by the Suzuki Corporation to an opening concert of the music hall built by a famous pianist: Doumoto Kazuki. The biggest attraction of this concert is a world famous Stradivarius violin and a special appearance of a singer who has perfect pitch, Akiba Reiko. The Detective Boys manage to convince her to coach their school performance. However, it seems someone is trying to kill Miss Akiba as Genta drinks poisoned tea meant for her after their training and a cargo truck tries to run them over during their way home.
