After an absence of four years Kinpachi Sensei, everyone's favorite teacher, returns to the television screen in a new series. When the series first went into production in 1979, delinquency and on-campus violence were big social problems. Over the years, the pressing problems became truancy and bullying, and more recently, disorderly conduct in classrooms and children with explosive tempers. Kinpachi Sensei returns to the classroom to help teenagers caught between childhood and adulthood, who suffer many social and emotional strains.
