Shinichi Kudo is a uprising high school detective, famous for solving every case he comes across. But the most recent crime he encounters, a murder on a roller coaster, brings him on the tracks of a large criminal organisation with a mysterious super drug: a untraceable poison. The clash between the two sides is unavoidable and sadly Shinichi has to experience the effects of the poison first hand. Lucky for him, the unusual side effects of the pill don't kill him, but change his live drastically. At least he can count on the help of his childhood friend, who never left his side that night.
