Peter and his latest partner, Marty Stramm, are tracking a gun dealer trading dangerously advanced weapons. Stramm is a good cop, but the stress of the job is making him abusive towards his wife, Emily. Kwai-Chang offers Emily support, and her self-esteem is boosted as he starts to teach her kung fu, but Stramm reacts explosively and beats her during an argument. Peter and Stramm succeed in apprehending the gun dealer, but Stramm is horrified when his son, Billy, appears outside the police station with a gun, determined to protect his mother. Kwai-Chang and Peter manage to prevent a shootout, and Stramm quits the force rather than continue to endanger his family.
