Amidst a pitch-black night, a spy successfully penetrates the Japanese police force with the motive of snatching confidential information from various intelligence agencies, including MI6, BND, CIA, and FBI. However, Tooru Amuro and his team effectively thwart the scheme, initiating a high-speed pursuit on the highway. Just when a calamitous accident seems inevitable, FBI agent Shuichi Akai makes a precise shot, abruptly halting the chase. The subsequent day, Conan and his companions visit a newly renovated aquarium in Tokyo. While exploring, Conan comes across a stunning stranger who seems wounded and suffers from amnesia. Unusually, the woman's eyes vary in color, and she cannot remember her name or communicate via her shattered mobile phone. As they vow to aid her in recovering her lost memories, they remain unaware of Vermouth, who watches from the shadows with a silencer in hand. Speaking into her attached intercom, she declares, "Everything is unfolding as planned, Gin."
