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.
