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.

Following an anonymous tip, Richard Moore travels to a remote inn to catch a murderer. Instead he finds evidence of river monsters! Conan is sure the killer is all too human, but then Rachel sees one of the legendary creatures for herself…

Then Conan visits a hot spring where a movie crew’s crime drama is interrupted by a real murder. And at a romantic chocolate-themed party, the host samples a not-so-sweet bite of cyanide!
