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.

Harmon Rabb is promoted and his first assignment as Lt. Commander is to defend Capt. 'CAG' Boone in a court-martial. During a mission over Bosnia, one aircraft goes down due to a system malfunction. A Serbian helicopter shoots at the parachuting crew and, to protect them, the CAG shoots down the helicopter. Is CAG, indeed, defending the crew from a hostile helicopter, or is he acting out of revenge, violating a cease-fire, and risking a war? Locations: Bosnia; Naples, Italy; USS Seahawk/Adriatic Sea; Washington D.C.

Having been shot at by Russian fighters, Mac & Harm are forced to eject from their plane, which then noses into the bottom of a very deep lake. The Russians announce to the world that Harm & Mac have been killed, which is broadcasted back to the USA by ZNN reporter Chuck DePalma.

Webb tries to convince the Admiral that they have been killed, but when A.J. learns their bodies haven't been found, A.J. becomes irate and vows to go to Moscow himself to look for them. The SecNav orders A.J. not to go, who replies that the SecNav doesn't want to try & stop him.

In Russia, A.J. meets with DePalma who tells A.J. that he doesn't believe the Russians, that certain things in their story don't add up.

In the woods, a husband & wife gypsies come across Harm & Mac. They are disappointed when they learn that Harm & Mac are not American Spies as at least the spies have gold coins to give to Russians that help them.
