JAG (Judge Advocate General) is an elite legal branch of military officers trained as lawyers who investigate, prosecute, and defend those accused of military crimes, including murder, treason, and terrorism. Navy Cmdr. Harmon "Harm" Rabb (David James Elliott), an ace pilot turned lawyer, and Marine Lt. Col. Sarah "Mac" MacKenzie (Catherine Bell), a strictly by-the-book officer, are partners with similar high standards who often find themselves clashing as they take different routes to solve cases. Along with colleagues Adm. A. J. Chegwidden (John M. Jackson), Lt. Bud Roberts (Patrick Labyorteaux), and Ens. Harriet Simms (Karri Turner), the JAG team is on the case -- aboard aircraft carriers, submarines, and on military bases -- investigating and litigating incidents involving Navy and Marine personnel. In the 24 episodes of Season 7 (2001-2), Cmdr. Sturgis Turner (Scott Lawrence) makes his first appearance, and Cmdr. Mic Brumby (Trevor Goddard) bids farewell to the JAG crew.
