The neon-lit streets of Tokyo set the stage for one of Detective Conan’s most perilous investigations yet. Shinichi Kudo, trapped in the juvenile body of Conan Edogawa, finds himself entangled in a high-stakes conspiracy involving the infamous Black Organization and a rogue high-tech security firm. The inciting incident occurs during a rainy midnight gala at the Mori Kogoro Detective Agency, where a terrified informant delivers a cryptic flash drive containing classified biometric data before being assassinated by a mysterious sniper sporting a distinct, cybernetic eyepatch.Driven by an urgent desire to dismantle the Black Organization and restore his true age, Conan teams up with genius inventor Professor Agasa and the enigmatic FBI agent Shuichi Akai. Meanwhile,
police inspector Megure and Officer Sato struggle to contain the mounting body count as the "One-Eyed Sniper" begins targeting key witnesses connected to a defunct government surveillance project known as "Project Flashback." Conan soon discovers that the flash drive holds the identity of a double agent operating within the upper echelons of the Japanese police force, making trust a luxury no one can afford.The investigation reaches a fever pitch when Ran Mori is inadvertently kidnapped by the syndicate, serving as leverage to force Conan into surrendering the decryption keys. Reluctantly joining forces with Haibara, whose radar for
the Organization's aura proves vital, Conan infiltrates an abandoned subterranean subway terminal beneath the bustling district of Ginza. The climatic showdown unfolds amidst screeching train alarms and blinding strobe lights. Conan uses his enhanced kick-enhancing shoes and tranquilizer-dart wristwatch in a masterclass of tactical ingenuity, ultimately turning the sniper’s own technology against him.During the chaotic melee, the true identity of the One-Eyed assailant is unmasked as a disgraced former public safety commissioner seeking vengeance against the government that discarded him. As explosive charges threaten to collapse the entire subterranean network, Akai provides crucial sniper cover, allowing Conan to rescue Ran at the very last second. Although the primary villain plunges to his demise, the encrypted data self-destructs just as Conan is about to access the master directory. The ordeal leaves Conan bruised and emotionally exhausted, standing on a damp Tokyo rooftop as dawn breaks. He realizes the Black Organization remains perpetually a step ahead, yet his resolve hardens. The flashback may have ended in smoke and mirrors, but the war for his true identity is far from over, setting the stage for an inevitable, catastrophic final collision between shadows and truth.
