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.

Harm and Mac investigate a female fighter pilot's charge of sexual harassment against her commanding officer.

The pilot, Lt. Marilyn Isaaks, claims to have been grounded for pressing charges of sexual harassment against her commanding officer, Capt. Boone (guest star Terry O'Quinn). Capt. Boone claims he grounded her because she's a bad pilot. While Harm and Mac are called in to conduct a thorough investigation into the allegations, congressional intervention forces Boone to schedule Isaaks for a training flight -- an action that Harm feels will have deadly consequences.
