While patrolling the Mediterranean near Yugoslavia and against the orders of Harm, his division commander, Lt. Buxton fires on what he believes is a Serbian armored car about to attack Kosovar refugees. As Buxton and his pals are celebrating his victory back aboard the aircraft carrier, however, the grave news arrives: those ""Serbs"" Buxton attacked and killed were, in fact, Russian peacekeepers, and Buxton made the mistake while under Harm's command.

Mac prosecutes what appears to be an open-and-shut case of a Marine weapons expert accused of reckless endangerment.

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.

Harms fitness report is coming up and the realization that maybe it really is too late to be a fighter pilot.

During a dangerous mission over hostile Serbian territory, Harm's wingman's plane is shot up and Harm performs top-gun maneuvers to keep the disabled plane aloft until it's over friendly territory.

Meanwhile, with a new Gunny in the office, Bud & Tiner fall over themselves as they compete against each other in an online auction to purchase tickets to a concert, in order to impress the Admiral. They end up looking foolish when it is discovered that the Gunny got the same tickets for free.

Trouble in the JAG office starts when Gunnery Sgt. Victor Galindez, ""Gunny,"" is charged with assault following an off-duty altercation outside a gay bar. It comes to light that P.O. Tiner was also involved in the brawl, having come to the aid of his companion, whom Gunny was roughing up.

Meanwhile, Mac finds herself wrestling with the ""don't ask, don't tell"" policy as attitudes toward Tiner change around the office under suspicions that he's gay.

Mac goes undercover to help Harm investigate charges of sexual misconduct against Chief Petty Officer Merker who is the leader of the Wiccans, a local witches coven with many Navy members. The female seaman who brought the charges claims she was seduced when she fell under the man's spell, but Merker claims the sex was consensual. The Wiccan's attorney is sharp and claims his client is the unfortunate victim. However, Mac learns that another young woman suffered the same fate. He convinces her to testify and Merker is found guilty.

Later, Mac learns that Mic Brumby was also thrown into a compromising position while undercover in the Royal Australian Navy.

Bud's underachieving brother is accused of making a mistake during a training exercise that nearly killed 15 Marines. But establishing his innocence proves to be a difficult task, thanks to the age-old tension between the Navy and the Marines.

Adm. Chegwidden frets over a speech he must give when he is to be given an award.

Mic Brumby returns unexpectantly to the States; Mac & everyone are stunned when he announces that he has resigned his Royal Australian Navy commission so that he could move to the USA and be by the "woman he loves."
