When skeletal remains are found in a void space on a mothballed carrier, Rabb and Mac must investigate this mysterious occurrence. However, during their investigation, Rabb falls through an unmarked hole in a corridor floor, giving him a concussion. Rabb must find his way out to receive medical treatment. He begins to see the vague shape an Officer who leads him not to safety, but instead to a crew birth which might provide the answer to decade's old cuddle.
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.
