JAG (Judge Advocate General): The Sixth Seasonbegins with a bang in the two-part "Legacy," a complex story that sees Commander Harmon "Harm" Rabb, Jr. (David James Elliott) sent to Russia to help the former Communist nation evolve its military justice system. While there, Harm becomes involved in an investigation of a corrupt general running guns to Chechnyan rebels while fighting them at the same time. What Harm doesn't know is that his work happens to be intersecting with an investigation by Lt. Colonel Sarah "Mac" MacKenzie (Catherine Bell) into the murder of an American naval officer tried for espionage. Everything is leading toward an assassination plot of global dimension, but there is a remarkable development in these episodes concerning Harm's efforts to find out more about what happened to his father, a naval pilot shot down over Vietnam. Following "Legacy," most ofThe Sixth Seasoncarries on with the series' typically  interesting stories about the prosecution of military law. But there are also some very strong personal developments, including a tragedy endured by Lt. Bud Roberts (Patrick Labyorteaux) and his wife, Lt. Harriet Roberts (Karri Turner). There are also major complications surrounding Mac's engagement to her Australian boyfriend, Lt. Commander Mic Brumby (Trevor Goddard). By complications, of course, one is really speaking of Harm's unexpressed feelings for Mac, a subject that finally comes to a head toward the end of the season, particularly in a cliffhanger finale taking place on the eve of Mac's wedding."Florida Straits" is a very good episode about Harm's investigation of a Cuban-American Navy captain who manipulates events so that a little Cuban girl can possibly qualify to live in the U.S. "JAG TV" finds Mac a television sensation when a court martial she prosecutes makes her a cable TV star. "The Princess and the Petty Officer" puts Mac squarely in the middle of America's relations with a Mideast nation when she defends a princess who left her arranged marriage back home to wed an American in the navy. The two-part "A Separate Peace" is an unnerving tale of a high-profile admiral (Terry O'Quinn), a friend of Harm's father, whose possible appointment to an important position is jeopardized by rumors he participated in the slaughter of innocent Vietnamese civilians decades before. The admiral doesn't help himself by being vague with Mac, who is trying to defend him. "Miracles" is an odd story about a Marine sergeant (Gerald McRaney) accused of  murdering his wife. Though the evidence points to him, the accused officer is defended by Harm in his claim that he did not kill his spouse but rather found her body after being led to her by the spirit of a former chaplain. Finally, "Lifeline" and "Adrift (Part 1)" bring Mac and Harm's true feelings for one another to the surface, forcing them to figure out what they're going to do now that Mac is getting married. Making matters worse is the terrible situation in which Harm finds himself after trying to fly through a terrible storm while Mac and Brumby host their pre-wedding rehearsal dinner.--Tom Keogh
