sister-in-law's deaths. She gets her hair cut short, trains herself in judo and karate, and enters Don's gang after deceiving the members into believing that she too is on the wrong side of the law. Without suspecting any ulterior motive, Don is impressed with her fighting skills and allows her to work for them all. After several years of unsuccessful attempts, the police finally succeed in nabbing Don who, however, tricks them all and flees from the spot. During a police chase, he is badly injured by a gunshot inflicted by the police which leads to his sudden disappearance.
