When a female F-14 Tomcat RIO (Radar Intercept Officer) goes missing from the aircraft carrier U.S.S. Seahawk while stationed in the Adriatic Sea, the Judge Advocate General of the Navy, Rear Admiral Al Brovo (Kevin Dunn), sends young Lieutenant Harmon Rabb with Lieutenant Junior Grade Caitlin Pike on Bastille Day 1995 out to the carrier where they must find out whether her death was accidental or intentional.

Harm & Kate continue to investigate the death of Lt. Angela Arutti, all the while the carrier remaining on combat status.

A civilian tech rep aboard a submarine seizes control of an experimental torpedo after its launch during an exercise. The rep threatens to sink a cruise ship and demands a ransom. Harm and Ltjg. Meg Austin go to the sub and save the day.

Harm teams up with Maj. Sarah MacKenzie and Lt. Roberts to investigate, together with Special Assistant Webb, the theft of the Declaration of Independence, which was stolen by Colonel O'Hara. O'Hara, who turns out to be Mac's uncle, claims he has taken control of it to remind the people - and especially the politicians - of its meaning and spirit. Locations: East of Yuma, Arizona; Red Rock Mesa; Washington, D.C.; Falls Church, Va.

Word of her father's imminent death forces Mac to look back at the years of anger and resentment he caused her. She is furious that a priest is trying to convince her to forgive this abusive alcoholic, who was responsible for her own alcoholism. She comes to realize, however, that perhaps her anger had been misdirected all these years when her mother shows up -- after having abandoned Mac many years earlier.

Meanwhile, Harm takes a gamble and undergoes laser surgery as a possible cure for his night-blindness.
