A wedding ceremony is being held in Shibuya’s “Hikarie”.

The bride, Sato, a detective of the Metropolitan Police Department, is in a wedding dress.

While Conan and other the guests are watching, a group of thugs suddenly invade the venue and attack. Detective Takagi puts himself in danger and risks his life to protect Sato.

Though the situation is settled, and Detective Takagi is safe, Sato is reminded by the incident about the series of bombings from three years ago; the ones that killed Detective Matsuda, her first love.

At the same time, the criminal behind the bombing incident three years ago, has escaped prison. Is this a coincidence? Rei Furuya (Toru Amuro) of the Public Security Bureau hunts down the person who killed his colleague, Detective Matsuda. However, another person in a mysterious costume appeared, and attached a collar bomb on him.

Conan visits an underground shelter where Amuro is hiding to safely remove the collar bomb. Amuro tells Conan about the incident from three years ago: the encounters with an unidentified costume bomber “Plamya” in Shibuya with his fellow Police Academy members. Eventually, a disturbing shadow is cast upon Conan and others who are proceeding with the investigation…
