The movie will focus on Ai Haibara's past and will reconstruct the Mystery Train arc from the television anime, which shows Haibara and Conan meeting for the first time. The movie will also include scenes from the Kurogane no Submarine (Black Iron Submarine) movie. (Source: MAL News)

After receiving a strange invitation, Kogorou Mouri pays a visit to the Miracle Land theme park along with his daughter Ran, Conan Edogawa, and the Detective Boys. Once there, Kogorou and Conan are tasked with finishing an unsolved case by a mysterious stranger. Realizing that the invitations were actually an elaborate trap, the two have just 12 hours to solve the case or face grave danger. With the help of familiar faces like Heiji Hattori, Kaitou Kid, and even Saguru Hakuba, the group of detectives must unravel the web of clues surrounding the case in order to find the culprit and bring them to justice before it's too late.

Kudou Shinichi is living his life as Edogawa Conan, but those days seem like they might end pretty soon. The Black Syndicate is coming dangerously close to learning the truth about Shinichi having survived. Conan and everybody around him may end up dead if he doesn't manage to find Irish—a member of the Black Organization who has infiltrated the police forces, currently investigating a big serial murder case.

Conan Edogawa is facing a dilemma: Ran Mouri has asked Shinichi Kudou out to the movies and he is unable to provide a convincing excuse not to go. However, when the day of the date arrives, he has more pressing problems to worry about—a great amount of plastic explosives has recently been stolen and the culprit has challenged Shinichi to find and dispose of the bombs he has scattered across the city. Now forced in a race against time, Conan must not only protect the city, but also figure out who the mastermind is and his reason for confronting Shinichi.
