Can Detective Conan crack the case…while trapped in a kid’s body?

Jimmy Kudo, the son of a world-renowned mystery writer, is a high school detective who has cracked the most baffling of cases. One day while on a date with his childhood friend Rachel Moore, Jimmy observes a pair of men in black involved in some shady business. The men capture Jimmy and give him a poisonous substance to rub out their witness. But instead of killing him, it turns him into a little kid!

All the while, he's looking for the men in black and the mysterious organization they're with in order to find a cure for his miniature malady.

Meanwhile, there’s a new teen detective in town. The mysterious Sera has Conan’s deductive genius and Rachel’s skill at martial arts! Can Conan and Rachel solve a case at a haunted hotel before their new rival, or have they been out-sleuthed at last?
