A civic music group, created by Tsukasa Nitta, a high school teacher in Koriyama City, and Akiko Watanabe, the daughter of a record shop and teacher of a music class, invites Takuro Yoshida to Koriyama City to hold a concert. He then starts being harassed by the Hashimoto group, a local gangster group which manages the city's entertainment.
Two lovable idiot "private detectives" (or at least, that's their cover story —more like gangsters) try to make ends meet on the mean streets of Tokyo.
