Meitantei Conan Movie 06: Baker Street no Bourei

A private demonstration of the virtual-reality game Cocoon gathers fifty children, including Conan, Ran, and the Detective Boys. The celebration turns into a murder investigation when a company employee dies after leaving a clue pointing toward the game's recreation of 19th-century London.

Once the children enter Cocoon, the artificial intelligence Noah's Ark seizes control and declares that failure inside the simulation will kill every player. Conan must follow the trail of Jack the Ripper through Victorian London while solving the real-world murder at the same time, knowing that the lives of all fifty children depend on reaching the truth before the game ends.
