The guard named Zenkichi Ooka is threatening two people to keep giving money to him. At night, Conan, Ran, and Kogoro came from the store after they had delicious spring rolls.

At Ristorante Sundayrino, Raita Banba and Hatsune Kamon are getting married. Kogoro, Ran, and Conan are also there. Everybody is having a great time with them. Later, Kogoro, Ran, and Conan are introducing themeselves to Kamon at the table. Ran heard that it was love at first sight for Banba and Kamon. As the night progresses, Banba receives a 'Goodbye' text message from Kamon. Outside, suddenly, Kamon's car exploded, right before Conan's eyes.
