Takagi and Miyamoto poses as a bride and groom in order to catch a serial killer/burglar who had threatened to kill the real bride and groom. When Chiba reports that the burned corpse of one of the wedding guests is found near the river, Megure deduces that the victim was killed by the serial killer in order to obtain the wedding invitation. A mysterious video arrives at the wedding party from a friend of the groom. After watching the video, Megure suspects that the killer is already in the chapel and Conan suggests that the bride meet with the guests in order to find the burglar who broke into her house. The bride reports that there are three suspicious guests: a photographer, a snowboarding instructor, and an internet administrator. The groom insists that the wedding to proceed, despites Megure's protests. As the bride walks down the aisle, the burglar suddenly appears. However, the groom announces that the burglar was actually a police officer, Chiba, posing as the burglar. Megure points out that Chiba has been by the river and the groom could not have figured out the burglar's true identity. Megure also reveals that the groom was the burglar's accomplice and in the end killed the burglar so he could marry the bride for money. When the groom attempts to escape, he is stopped by Conan and Ran.
