Ran and Conan plan to meet Heiji at a cafe, however the train has had problems and he is late. While they are sitting there, a worker named Miki Tosawa accidentally dumps juice onto Conan. Miki then invites them over to her house and tells them that she actually was planning on going to the famous detective Kogoro Mouri for help, because her sister Satomi has disappeared without telling her where she was going. Conan puts together some clues that lead them to the book store where Haibara helps them locate a guidebook to a really old temple where they think the sister has gone. Then, later, joined by Kogoro and Heiji, Conan, Ran, and Miki set off for the temple in search of the missing Satomi. [From Detective Conan Wiki]
