One of the dead is a friend of Harm, who seeks to protect the family and the reputation of his friend. Clayton Webb, the CIA, a submarine, counter-espionage, and disinformation are involved. In a preliminary hearing Harm represents the government, and Bud represents the suspect, who is the one who survived the shooting. Harm figures out what happened. Meanwhile Renee returns from Minnesota with a big surprise, and Mac returns from Indonesia but soon goes back. Mac also receives a significant medal, but she gives it away.
