Detective Conan: Episode One - The Great Detective Turned Small

Intrigued by what was going on, he quietly followed one of the men, hoping to learn more. The criminals, members of a mysterious organization, could not allow anyone to uncover their secrets. Instead of simply killing the young man, they decided to use a new poison on him, an experimental pill that they believed would wipe him off the face of the earth. The poison, however, worked in an unusual way: instead of dying, Shinichi's body shrank, turning him into a child of about seven. Thus began his new life under the name Conan Edogawa, a life full of danger and secrets, and of a struggle to regain his former body and uncover the secrets of the Black Organization.
