After winning free tickets for a preview showing of the latest Death God Jinnai movie, Kogoro, Ran and Conan visit the cinema. Outside, when the movie's over, Kogoro is approached by Nanjo Miyuke, the wife of the movie's star. She recognises Kogoro as a great detective and would like him to investigate a death threat her husband, Nanjo Hayato, has received. The death threat is signed "Death God Jinnai," the character Hayato plays in the movies. However, Hayato refuses Kogoro's help, believing that the threat is not genuine. That evening though, the threat is carried out and Hayato is found dead in his apartment. Was this the act of a crazed fan or somebody closer to home?
