Case

Situation

In Frankfurt, an Europol agent is being chased by Kir and Gin. Although Kir tries to help her escape, Gin eventually murders the agent. Some time later, Conan, Ran, the Detective Boys, Agasa, and Kogoro are invited to the resort at Hachijo-jima, owned by Sonoko's family. Conan later receives information from Subaru about the Europol agent who was murdered and a new Black Organization agent known as Pinga is on the move.

Murder

Location: Frankfurt, Germany

Victim: Nina Balmer

Cause of death: Gunshot wound

Culprit: Gin

Kir had attempted to spare Nina Balmer, but Gin shot her by firing a bullet through Kir’s shoulder which struck Nina in the head.

Having discovered Shiratori and Kuroda, Conan secretly went after them to an Interpol underwater facility known as the Pacific Buoy. The facility hosts a new state-of-the-art system that allows them to connect to all the surveillance cameras in Japan, Europe, and eventually all over the world. Headed by Yosuke Makino, four other engineers (Ed from India, Grace from France, Leonhardt from Germany, and Naomi Argento from United States) also work in the facility. Another function of the system is the "All-Age Recognition" system, which uses facial recognition and AI reconstruction of a person’s facial structure to identify individuals whose age may have differed from the source material.

At the same time Bourbon and Vermouth have secretly infiltrated the Pacific Buoy and arranged for the kidnapping of Naomi Argento, holding her captive in a submarine. They along with Vodka and Kir discover from Naomi's flash drive that was hidden in her necklace that the All-Age Recognition system had apparently identified Haibara as Shiho Miyano.

Kidnapping

Location: Pacific Buoy, Hachijo-jima, Japan

Victim: Naomi Argento

Culprits: Vermouth and Bourbon

Vermouth and Bourbon secretly kidnapped Naomi from the pacific buoy by knocking her unconscious.

That same night, Chianti, Vodka, and Pinga kidnap Haibara from Sonoko's resort. Conan and Agasa try to chase after them, but unfortunately witness Vodka and Pinga driving their vehicle with Haibara into the sea to board their submarine underwater. The incident was reported to Kuroda, and Conan asked to use the Buoy's surveillance system to check the security cameras on the route of the car chase and the presence of the submarine, but they discovered that no submarine or vehicles were caught on the camera, seemingly indicating that the system had been tampered with.

Kidnapping

Location: Hachijo-jima, Japan

Victim: Ai Haibara

Culprits: Vodka and Pinga

After discovering that Haibara and Sherry were one in the same, Vodka and Pinga drugged Haibara and kidnapped her.

However, Leonhardt had figured out who the person responsible for tampering with the surveillance footage was and tried to confront the culprit, but was drugged and was seen on the cctv camera committing suicide via poisoning in the Buoy's Cafe. The confession letter apparently written by Leonhardt also mentioned that he was responsible for the Backdoor in the Buoy's system.

Suicide?

Location: Pacific Buoy, Hachijo-jima, Japan

Victim: Leonhardt

Cause of death: Poisoning

Suspects: Grace, Ed, and Yosuke Makino

Conan and the others witnessed Leonhardt apparently committing suicide by taking a poison capsule.

Meanwhile, Vodka tried to force Naomi to tell them how to use the All-Age Recognition program, and when she refused to do so, he arranged for her father, a member of the European Parliament that proposed the use of the surveillance system, to be killed.

Murder

Location: Frankfurt, Germany

Victim: Mario Argento

Cause of death: Shooting

Culprit: Korn

Naomi was forced to watch as Korn murdered her father.

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 other people with similar faces, but not necessarily the same person, indicating that the system is flawed. Frustrated by this development and following orders 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 had escaped from the submarine using the clues provided by Kir.

Conan went back to the Buoy and revealed through Kogoro that the person who murdered Leonhardt is Grace. Grace murdered Leonhardt as he had examined the access log and discovered that Grace was the only person who accessed the camera footage. Grace is then revealed to be Pinga, who used the Deepfake method to fake Leonhardt’s suicide footage and tried to escape from the Buoy. With the submarine set to attack the Buoy, Conan tries to light the position of the submarine from underwater and arranged for Akai to launch a rocket that severely damaged the submarine, forcing the Black Organization to flee from the submarine. Pinga dies from the blast when the submarine exploded as Gin had intentionally left him there to die. Conan later loses consciousness underwater, only to be rescued by Haibara who went after him and took him to the surface.

Murder

Location: Underwater

Victim: Pinga

Cause of death: Explosion

Culprit: Gin

Pinga died from the submarine after it was set to self-destruct and the fact that Gin had purposely left him to die.

During the mid-credits scene, the Detective Boys reunite with Conan and Haibara. Jodie is seen visiting Nina's grave with Hans. It is revealed on the news that Naomi's father had survived the attempted murder by the black organization.

In the post credit scene, the Pacific Buoy project is reported to have been 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. Furuya told Conan that the flaw in the system is revealed to have been staged by Vermouth, who disguised herself as Sherry and appeared in security camera footages around Shibuya, Okinawa, and Manila, to hide the fact that Haibara is Shiho Miyano. An elderly woman whom Haibara earlier in the movie had offered her ticket to purchase a Fusae Campbell-branded ginkgo leaf pin is revealed to be Vermouth, who thinks to herself that Silver Bullet should figure out the reason she helped fabricate the flaw in the system himself.

Music

The soundtrack is directed by Yugo Kanno, who took the role from Katsuo Ohno in the previous movie.

The ending theme is titled Utsukushī Hire, song by Spitz.
