The Tokyo Summit is about to be held. In order to ensure the smooth progress of the meeting, the Japanese police dispatched about 20,000 police officers to carry out security work at the super-large facility "Ocean's Edge" in Tokyo Bay. However, under strict prevention and control, an explosion has already occurred here. What Conan (voiced by Takayama Minami) and others did not expect was that the scene actually left extremely unfavorable evidence to Maori Kogoro (voiced by Koyama Riki). After that, Kogoro was arrested. Conan discovered that Amuro Toru had appeared at the explosion site and was injured. In order to clear Uncle Maori's innocence, Conan and Dr. Agasa and the friends of the Junior Detective Team jointly investigated the scene and collected evidence. As the investigation deepened, Conan discovered that the explosion case concealed a complex relationship between multiple parties including terrorists and public security, and the truth made everyone dumbfounded... This film is the 22nd animated theatrical version of the "Detective Conan Series", with a total box office revenue of more than 9 billion yen.
