The Kanto region is in ruins after a devastating earthquake. Amid the chaos, a criminal known as the Slum King abducts women and forces them into sexual slavery. Mari searches the wreckage for her lover, Ken, but she too is captured and subjected to brutal training. Ken, now a member of the Slum King's gang, rescues her. The king makes him an offer: if Ken kills the infamous Violence Jack, Mari will be set free.
