Houston Knights

The Vietnamese community is up in arms when three of their immigrants are murdered. All clues point to a Vietnam veteran with a history of violence. Neither the tight-knit community nor the vets are interested to cooperate with the police. When the Knights go to talk with this veteran, Joe and the man end up in a stand-off, each man aiming a gun at the other. A nurse who served with the man, helps to talk him down. Later as the Knights talk with the nurse and others, they discover the doctor who has been counseling these veterans has been interested in every aspect of killing someone. The veterans say the doctor is more violent then they are. The doctor goes to pick up the nurse because he thinks she is attracted to him but when she refuses him, he threatens to kill her. Joey kicks in her door and kills the man.
