High schooler Shinichi Kudou is renowned for his exceptional detective work, having already cracked multiple difficult cases.
When Shinichi chooses to follow two individuals he thinks are acting suspiciously, he finds himself unwittingly witnessing a terrible illicit operation. When he is arrested, the men decide to experiment on him with a new drug that their criminal organization has developed, and then they abandon him to his fate.
The only reason Shinichi makes it through the ordeal is because he has the body of a seven-year-old child, much to his own surprise.
His original IQ is perfectly preserved as he fools everyone into thinking he is someone else, including his childhood friend Ran Mouri and her father, private detective Kogorou Mouri.
Conan Edogawa is a nickname he adopts after being influenced by the works of Ranpo Edogawa and Arthur Conan Doyle, two of the most famous mystery authors in Japan.
