Unexpectedly, the wily Buxton demands that Harm and Brumby be his lawyers, thereby preventing Harm from testifying against him and forcing the two adversarial lawyers to work together. The contentious trial continues with Mac and Roberts prosecuting, and the pressure is enormous as the U.S. Navy and the Russian government vigilantly follow the trial to ensure that its own agendas are met. Meanwhile, the Navy has its own special plans for the troublesome Buxton.
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.
