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

When ace high school detective Jimmy Kudo is fed a mysterious substance by a pair of nefarious men in black—poof! He is physically transformed into a first grader. Until Jimmy can find a cure for his miniature malady, he takes on the pseudonym Conan Edogawa and continues to solve all the cases that come his way.

After missing one hint after another, Conan finally gets a clue and remembers where he first met Sera, the girl detective with the mysterious past. Flash back to a childhood trip to the beach and watch young Jimmy Kudo track down a robber with the help of a very unusual family.

Then Mr. Moore gets into a battle of wits with a mystery-loving sushi chef, and the Detective League investigates a murder at their new teacher’s condo building. Which of these cases will bring Conan another step closer to Rum, second-in-command of the Men in Black?
