Harm is called in to probe the death of Navy pilot Lt. Marion, son of US Senator Grace Marion, while training with the Navy SEALS. As he was there only for two days, it seems that the death was due to gross negligence. With the reports given by his superior and comrades, combined with the results of how how he died, it seems that the actual incident is a cover-up. Analyzing his equipment and learning that it was a combat mission (and not a training mission as stated), the facts then point at murder. The key to all this could be General Behnke. Locations: Washington D.C.; NAS Roosevelt Roads, Puerto Rico; Carribean Sea; Colombia

And since there isn't another eligible pilot, Lowry cannot be removed from the team. A training flight with Lowry and Harm on board has a fatal system malfunction - again sabotage. Lowrey can now be crossed out but the person responsible for these incidents must be found as the scheduled mission must proceed as planned. It is highly possible that there will be another 'unpleasant surprise' to stop this mission. Locations: AFB Vandenberg; Space

Willie, a very complex individual, has been waiting 30 years to tell his story in his own way.

International tensions mount as Harm, Mac and Bud board an aircraft carrier in the Sea of Japan to investigate the accidental shooting down of a North Korean civilian airline by Navy jets.

While negligence on the part of the Navy fliers is indicated, Harm and Mac uncover evidence of a spy aboard the carrier.

Harm and Mac, in their investigation, find Rivers, an African-American, to be a very tough, complex and uncommunicative individual who is totally devoted to his country and his duty. But his men paint a different picture of him as a gung-ho loner who doesn't care about the safety of his team and, in fact, botched the mission by leaving one of his men behind. Rivers finally agrees to open up to Harm -- but only if Harm can withstand arduous SEAL training for one day -- including the brutal manhandling required of the ""hostage interrogation.""

Harm & Bud are sent to Twenty-nine Palms Marine Base to investigate the mid-air collision of 2 helicopters & subsequent crash of one helicopter which killed the pilot.

Upon arrival at the crash site, they learn that the ""other"" aircraft was not another helicopter as was first thought. A piece of wreckage that is found that belongs to the ""other"" aircraft only deepens the mystery. When members of the Defense Security Division appear onscene with orders to take over the investigation and crash site, Harm becomes convinced that a major cover-up is in the works.

The base commander, Col. Barrett gives Harm time to investigate further. When Harm & Bud are out driving the base at night, they see an unknown type aircraft flying above them and follows it, but are soon blocked by a fence over the road marking the property of the ""Bradenhurst Corporation"".

Harm meets with a Russian 'contact' in order to purchase documents that will prove his father was taken to Russia after being shot down in Vietnam. However, during the transaction, they are interrupted by a KGB agent, Col. Parlovsky who shoots & kills the Russian, then runs off as FBI agents show up, finding Harm over the body, with the gun & documents he wrestled away.

As the FBI wants to hold him for the murder of the Russian, Adm. Chegwiggen manages to have Harm transferred to a military brig, and court-martialed, much to the dismay of the FBI agents. CIA agent Clayton Webb, knowing that it was Parlovsky, not Harm that committed the shooting, arranges for Harm to escape from custody in hopes Parlovsky will contact Harm.

In the end, Parlovsky makes contact with Harm, but they both get away before Webb can catch them. Parlovsky tells Harm the documents were a fake and burns them. He then leaves, refusing to help clear Harm of the shooting.

Harm's skills as a lawyer are challenged when he defends a female ensign who claims she murdered an officer because her ""instincts"" told her he meant to hurt her.

The ensign claims that when the officer entered her apartment on false pretenses, she felt threatened by him and killed in self-defense. Though the defense is decidedly thin -- no weapon was even found on the man's body -- Mac and Harm decide to stick with the case and are determined to help the ensign remember forgotten details of the event.

Annie Pendry, a widow, comes to Harm for help after her young son, Josh, witnessed a murder while on a class trip to Andrews Air Force Base.

In order to solve the case, and combat Lowne's dirty tricks, Harm enlists the aid of Congresswoman Bobbi Latham. Justice is served, though many people's lives are changes as the result of Lowne's tactics.

Following her ugly break-up with Dalton Lowne, Mac has reason to believe that he's stalking her -- until he's killed during an apparent car-jacking and the stalking continues.

Mac arrives at Harm's apartment and is surprised to see that he has forgotten she was coming over and that he is getting to leave with a firearm. Stalling him, she gets him to tell her the story 2 years ago of the murder of his then-girlfriend, Lt. Diane Schonke, an Academy classmate, after her ship, the USS Seahawk docked in Norfolk. When Harm shows Mac a picture of Diane, Mac is stunned to see that Diane looks just like her.

When Harm tells Mac that he believes he has finally figured out who the real murderer is (Agent Turque) and that he intends to confront him, she gets him to initially agree to take her with him. Harm however tricks her and drives off, leaving Mac behind standing in the rain. Desperate to find Harm before he does something he'll regret, Mac calls Bud to meet her at JAG. Bud was an Ensign on Diane's ship and was one of the people who found Diane's murdered body. Bud tries to help Mac fill in the gaps and helps Mac learn that Agent Turque isn't the murderer.

Clark Palmer, a renegade government agent, breaks into Harm's apartment and incapacitates him. Palmer then makes a cast of Harm's face in order to prepare a mask that he can wear to pass for Harm. Palmer plans to murder the key witness in the trial at which Harm and Mac are currently prosecutors.

When Harm doesn't show up for the start of the trial, Mac takes his place, leaving Bud to search for the missing JAG lawyer. When Bud finds Harm trapped in an ingeniously booby-trapped apartment, the two must find a way to escape before the assassin can carry out his plan.

Members of the JAG team encounter resistance from Navajo tribal elders when they insist on DNA testing to verify that human remains are those of heroic Navajo ""code-talker"" Jimmy Blackhorse, who has been missing since World War II. Forensic pathologist Lt. Cmdr. Teresa Coulter joins Harm and Mac on the case.

The Navajo elders consider it a sacrilege to tamper with the remains of the dead and, furthermore, the Navajo medicine woman is certain that the remains do not belong to the esteemed Blackhorse. While the veracity of scientific evidence is argued against that of tribal custom and the metaphysical, Teresa finds herself falling for Harm and putting the entire assignment in jeopardy.

Clayton Webb meets with Harm at JAG and tells him who the men in the photo are. Webb mentions that one of them, Victor Lushov is now working in San Diego. Harm requests from the Admiral to take an F-14 hop to San Diego to visit his mother, keeping secret his true intentions.

In San Diego, Harm meets with Lushov who turns out to be a Russian pilot who was instrumental interoggating Harm, Sr. after he was shot down over Vietnam, later befriending him. He tells Harm Jr. all about what happened to his father, that Harm Sr. fed all kinds of disinformation to the Russians, which was worse than telling them nothing. Lushov gives Harm Jr. the KGB file number for his father. And says he wants to live and will not repeat what he has said to anyone.
