### Summary
Brilliant high school detective Shinichi Kudo's life is turned upside down during what should have been a simple date with his childhood friend, Ran Mouri. After solving a murder on a roller coaster, his sharp eye catches two suspicious men in black conducting a shady transaction. Leaving Ran to investigate, Shinichi is ambushed from behind. The mysterious figures force-feed him an experimental poison and leave him for dead, but the drug has an unexpected side effect—instead of killing him, it reverts his body to that of a young child, trapping a genius mind in a first-grader's body.
