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! Jimmy takes on the pseudonym Conan Edogawa and continues to solve all the difficult cases that come his way. 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.

Conan enters a mystery contest where he must be the first to discover the true identity of the enigmatic Night Baron. But the fun and games end when the contest turns into a real-life murder.

Later, Rachel's high school teacher is about to get married. But the wedding bells stop ringing when someone tries to murder the beautiful bride.

All the clues are there -- can you figure out whodunit before Conan does?
