it's about a detective (17 year old shinichi kudo), that get's strunk to a little kid (Conan Edogawa). then he stayyes with his "girlfriend" ran, who doesn't know that he actually is shinichi. Just a proffesor, I can't remember his name, knows about Conan and Shinichi, and helps Conan/Shinichi by giving him some special "super shoes" and a watch whiche can shoot out some sleeping stuff (forgot the name) and a rebon whiche he can use to talk in another voice. ran's dad is a detective too, but a very stupid one... but he became famouse, because Conan always shoots him to sleep, and then solves the case etc. and then this guy will wake up and like... "huh? waht happened? I solved this case?... ahahaha!! I'm so great!!!" he's so pathetic... anyway, then the story goes on like that.
