LCdr. Jordan "Jordi" Parker, a Navy psychologist and one of Harm's former girlfriends, leaves a voice message for Harm. When he calls back, he learns that Jordi has died. The NCIS first treats him as a suspect but later clears him. The admiral orders a JAG inquiry parallel to the NCIS investigation; Mac runs it, Bud helps, and, later, Harm does too. The NCIS calls it suicide. Harm calls in LCdr. Teresa Coulter, a pathologist, to help. After checking out three other suspects, the JAG team eventually find the surprising killer. Meanwhile in a criminal trial the admiral testifies against Danny Walden, the son of Dr. Sydney Walden, one of the admiral's former girlfriends, and he provides a practical alternative for the sentence for Danny.
