An old Navy pilot buddy of Rabb's makes an emergency landing in Cuba while testing new software for F-14's. Now the Cubans have the test pilot and an upgraded Tomcat. Rabb, Austin, and Krennick are sent to Cuba along with a State Department official to negotiate the return of the pilot and the fighter. Unknown to the others, Rabb is secretly told to destroy the fighter before the Russians acquire the software for themselves. However, this actually puts Rabb at odds with a CIA covert operation involving his pilot buddy.
After being diagnosed with night blindness, Lt. Cmdr. Harmon Rabb, an F-14 Tomcat fighter pilot, is forced to change careers. Cmdr. Rabb chooses to join the Navy's Judge Advocate General (JAG) Corps. There he both defends and sometimes prosecutes Navy and Marine Corps defendants. He is sometimes assisted by fellow lawyer, Lt. Sarah "Mac" MacKenzie, and his other fellow JAG staff.
Many of Rabb's cases require him to both keep up his F-14 qualifications and travel the world, in order to bring justice to the cases he is trying.
Rabb must also deal with the fact that his father, also a former Navy pilot, never returned home after being held prisoner after he was shot down in North Vietnam. Rabb believing his father is still alive continues the search he has pursued to find his father, since his teens.
