Sonoko has met people on the Internet that are magic lovers. She is invited to a mansion up in the snowy mountains for a meeting of the Magic Lovers Club. Sonoko goes there with Ran, Conan, and Kogoro. When the girls are dropped off, Conan and Kogoro leave to go back home because Conan has the flu. On the way back, Conan and Kogoro hear on the radio that a murder has been committed at a person's house. The radio describes that the person was a part of the Magic Lovers Club and was on his way to the meeting with his fellow club members. Kogoro and Conan know then that there is going to be trouble back at the mansion. So Kogoro turns the car around and drives back to the mansion with Conan. When they arrive however, they see that the only entrance to the mansion, a bridge, is burning down. Knowing what could happen to Ran, Conan rushes across the bridge and yells for her. Ran hears him and runs outside only to find Conan fainted on the cold snowy ground, the bridge destroyed.
