Plot
In Frankfurt, an Europol agent is being chased by Black Organization members Kir and Gin. Gin eventually murdered the agent. Some time later, Conan, Ran, the Detective Boys, Dr. Agasa and Kogoro are invited to the resort at Hachijo-jima owned by Sonoko's family. Conan later received information from Subaru Okiya that an Europol agent is being murdered and a Black Organization agent known as "Pinga" is making the move. Having discovered Inspector Shiratori and Chief Hyoue Kuroda from Tokyo Metropolitan Police, Conan sneaked after the two to an Interpol underwater facility known as Pacific Buoy. The facility hosts the new system that allows connection to all surveillance camera in Japan, Europe, and eventually worldwide. Headed by Yosuke Makino, four other engineers (Ed from India, Grace from France, Leonhardt from Germany, and Naomi Argento from United States) also worked in the facility. Also available is the "All-Age Recognition" system, which uses facial recognition and AI reconstruction of facial structure to identify individuals whose age may have differed from the source material.
Bourbon and Vermouth infiltrated Pacific Buoy and arranged for the kidnapping of Naomi Argento, holding her captive in a submarine. Vodka and Kir then discovered from Naomi's flash drive necklace that the All-Age Recognition system is able to identify Haibara as Shiho Miyano. The same night, Chianti, Vodka and Pinga kidnapped Haibara from Sonoko's resort. Conan and Dr. Agasa tried to chase after them, but discovered that Vodka and Pinga plunged the vehicle with Haibara into the sea to board the submarine underwater. The incident was reported to Kuroda, and Conan asked to have the Buoy's surveillance capability to check the security camera on the route of the chase and the presence of the submarine, but they discovered that no submarine or vehicles were caught on the camera, seemingly indicates that the system has been tampered. Leonhardt tried to confront the culprit, but was drugged and later shown to have suffered poisoning to death in the Buoy's Cafe. The confession letter apparently written by Leonhardt also mentioned that he is responsible for the backdoor in the Buoy's system. Meanwhile, Vodka tried to force Naomi to rewrite the All-Age Recognition program, and when she refused to do so, he arranged for Naomi's father, a member of European Parliament that proposes the surveillance system, to be killed.
Later on, Vermouth informed Gin that after running the All-Age Recognition system once again, she discovered that the system is able to pick up the image of the person with similar faces, but not necessarily the same person, indicating that the system is flawed. Frustrated by this development and following order from Rum, Gin decided to use the submarine to destroy the Buoy. However, when he tried to confront Haibara and Naomi, he discovered that the two have escaped from the submarine under the clues provided by Kir. Conan went back to the Buoy and revealed via Kogoro that the person who murdered Leonhardt is Grace. Grace murdered Leonhardt as Leonhardt has examined the access log and discovered that Grace is the only person accessing the camera footage. Grace is then revealed to be Pinga and tried to escape from the Buoy. With the submarine setting to attack the Buoy, Conan tries to light the position of the submarine from underwater and arranged for Shuichi Akai to shoot the rocket that severely damages the submarine, forcing the Black Organization to flee from the submarine. Pinga dies from the blast when the submarine explodes. Conan later loses consciousness underwater, only to be rescued by Haibara who went after him and took him to the surface.
In the post-credits scene, it is revealed that Naomi's father survives the attempted murder, and Pacific Buoy project will be moved to another country. Naomi realizes that Haibara is in fact Shiho Miyano, a friend who shielded her from being bullied when they studied in the United States. The flaw in the system is revealed to have been staged by Vermouth, who disguised herself as Shiho and appeared in security camera footages to disprove the fact that Haibara is Shiho Miyano. Later, the elderly woman that Haibara met before is actually Vermouth on disguise with a ginkgo leaf brooch (Fusae Campbell pin) before closing the elevator door.
