When a test flight goes wrong and the pilot ishuged, Rabb and Austin must uncover whether the crash was due to pilot error or some other reason. The case is made even more difficult as the dead pilot was a close friend of Rabb's. Rabb must also comfort the pilot's wife and young son. It is during this period that Rabb realizes he still has strong unresolved feelings for his deceased friend's wife.
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.
