On a dark night, a spy sneaked into a Japanese police agency and stole top-secret data from top-secret documents recording important data from espionage agencies of various countries. Japanese police and FBI agent Hideichi Akai (voiced by Hideichi Ikeda) immediately began a chase with the spies. Finally, the fugitive's car fell off a cliff. The next day, Conan (voiced by Gao Shannan) and his friends visited the Dongdu Aquarium and found a beautiful woman injured (voiced by Tian Hai Youxi). The woman is in a state of amnesia and her mobile phone is damaged and unusable. Conan and others promised to help her remember, and while they were talking, Belmaud, a member of the black organization hidden in the dark, watched coldly. In the process of getting along, the woman's extraordinary skills and strange words and behaviors make Gray Hara sad (voiced by Lin Yuan Huimei) doubt her true identity. Just now a peaceful aquarium, people immersed in happiness, will think that with the recovery of the skills of that mysterious woman, they will soon be involved in the killing and chaos of the dark organization.
