Spoilers ahead
At a glamorous New York City auction, Vincent van Gogh’s Sunflowers—long believed lost to a World War II air raid—reappear on the market and spark a global buzz. Jirokichi Suzuki, accompanied by his niece Sonoko Suzuki, wins the bid with an astonishing $300 million and immediately reveals a bold plan: bring all seven Sunflowers together for a single, world-spanning exhibition. The event will be staged in a purpose-built gallery perched on a cliff in Japan, nicknamed Lake Rock, and it will be safeguarded by seven specialists, the famed “Seven Samurai,” charged with top-tier protection. The announcement sets the stage for a high-stakes game of art, risk, and loyalty.
During the press conference, the audacious Kaitou Kid crashes the scene by flinging a card onto the platform and slipping away amid a blinding flash. The eager young detective Shinichi Kudo steps forward to assist in escorting the Sunflowers, adding a layer of tension as the two undercover identities blur into one another. The chaos continues as a dramatic turn unfolds: a cargo-plane transfer of the Sunflowers to Japan is sabotaged when a bomb blows out the door of the cargo hold, sending the paintings spiraling into the sky. Conan Edogawa waits at the airport and tracks the scene as Kid descends—yet the painting is found abandoned by Kid and later retrieved intact, the plane landing without casualties.
Back in Tokyo, the saga shifts to a second display of Sunflowers in a Japanese gallery. A Kid card arrives at Kogoro Mouri, signaling a fresh bid to steal another Sunflowers. Ai Haibara engages with an elderly woman who visits the Sunflowers daily, a moment that intertwines personal memory with the ongoing caper. As the Sunflowers are moved again toward Lake Rock, Conan notices a Kid card left with the painting, suggesting the artwork has already been taken. Natsumi Miyadai examines the piece but cannot confirm its authenticity and decides to take the painting to her studio for further testing. The art heist intensifies when Kid reappears, stealing the second Sunflowers and issuing a ransom of ¥10 billion in cash to be delivered within two hours, a demand Suzuki accepts.
The ransom scene unfolds in an isolated hotel room where the cash lies untouched, guarded by the gallery director. The pressure intensifies as a hidden threat rises: water in a bottle increases despite the director’s drinking, and the room becomes a deadly trap. Conan and Inspector Charlie Bowles storm the room just as Kid appears outside the window, launching a tense pursuit. Kid disappears again, aided by the chaos and a media storm organized by Kid earlier. Suzuki ultimately decides to keep the Sunflowers exhibition on track even as concerns about a potential second attack and a phosphine-based danger loom.
On the day of the grand exhibition, Kid returns, briefly impersonating Shinichi to slip into the crowd and leaves another cryptic note that Conan later deciphers. The Seven Samurai are evacuated and locked down as a fire, triggered by a power failure, threatens the gallery. The investigation deepens when Koichi Azuma, Koji’s twin brother, is found dead after the Sunflowers are recovered, and Azuma confesses to killing his brother but denies involvement in the theft. As the gallery’s vaults fail and two Sunflowers become stuck, Kid acts to save at least one of them. With Ran Mouri Ran Mouri returning to the scene, Conan helps rescue the remaining painting, and the building—and the cliff it sits on—begins to cave in around them.
In the chaos, a dramatic moment unfolds: Ran is knocked unconscious as the structure collapses, while Conan uses an explosive football to induce a pressure change and carve a path through the submerged tunnel. The Sunflowers’ protective frame serves as a shield, allowing Conan to escape and be rescued by Ginzo Nakamori as he surfaces with the painting. Waiting for Conan’s return, Kid faces Inspector Charlie Bowles, and reveals the true mastermind behind the scheme: Natsumi Miyadai’s plan to destroy the Sunflowers because she believes they are fakes. Kid explains that Konosuke Jii—who saved the painting during the U.S. air raid decades earlier and was entrusted by Azuma’s grandfather to keep it safe—had hidden the truth, and the elderly woman involved was the same person Haibara spoke with earlier. Moved by the revelation and the long history surrounding the Sunflowers, Charlie lets Kid go, and the boy genius disappears into the uncertainty of the night, leaving behind a resolved mystery and a preserved masterpiece.
