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.

When Harm views the body of the severely neglected, abused and abandoned young girl, he unexpectedly becomes emotionally involved and decides to call in the help of Teresa Coulter to help him identify the child and find her killer.

After Teresa performs her own autopsy, she uncovers some clues to the girl's history that lead her, along with Harm and Mac, to the last place the child lived -- as well as to a recently released convicted child molester.

Harm reopens a 10-year-old murder case and unexpectedly incurs the wrath of the victim's daughter, his friend Lt. Cmdr. Teresa Coulter (Trisha Yearwood). Harm feels that the original trial attorney didn't dig deep enough into the case and as he pursues the investigation a new picture begins to develop.

Harm is stunned to learn that his former girlfriend, Lt. Cmdr. Jordan Parker has been found dead in her apartment, having been shot with her own gun.

Despite this evidence, Harm is unwilling to accept the premise that Jordan committed suicide & calls in Lt. Cmdr. Teresa Coulter to help examine the forensic evidence. Harm & Mac begin to look for possible suspects who would want to kill her, starting with her last boyfriend who had also been a patient of hers.

However, as each of the suspects are ruled out, they begin to look for other possibilities to explain her death. The investigation leads to a shocking discovery for Jordan's neighbor. Returning home, Harm is stunned to find a letter from Jordan in his mail. Jordan wrote & mailed it a few hours before she was killed; in which she tells Harm just how much she had valued their time together.
