After cracking down on troubled teens in his own school, Eikichi (aka GTO) goes home to the peaceful shores of Shonan to relax and escape the stresses of modern-day Tokyo. However, much like communities across the globe, even his hometown has not escaped the declining state of child services. In typical form, GTO decides to personally provide hard-knocks education to his old neighborhood with hopes of putting a group of troubled teens back on the track towards happiness.
