Meitantei Conan Movie 10: Tantei-tachi no Requiem

Kogorou Mouri accepts a mysterious client's invitation to a hotel beside the Miracle Land theme park, bringing Ran, Conan, and the Detective Boys with him. The pleasant outing becomes a hostage crisis when Conan and Kogorou learn that the ID watches worn by their companions contain explosives and that they have only 12 hours to solve an old case.

Other detectives, including Heiji Hattori, have been forced into the same game, while Kaitou Kid's shadow hangs over the clues. Conan must untangle a robbery, a murder, and the client's own hidden past before the deadline reaches the people enjoying the park without knowing their lives are at stake.
