Harm and Mac must don their diplomatic hats when they're dispatched to Tokyo to represent an ensign accused of raping a young Japanese girl. Once the trial begins, the disparities between Japanese and American courtroom procedures put Harm at odds with the ensign's Japanese defense attorney, in turn putting US/Japanese relations at an all-time low.

When what began as the trial of an ensign turns into a trial of the United States Navy, Harm and Mac realize that in order to defend the ensign from life in a Japanese prison, they must actually solve the rape case on foreign soil.

When Harm views the body of the severely neglected, abused and abandoned young girl, he unexpectedly becomes emotionally involved and decides to call in the help of Teresa Coulter to help him identify the child and find her killer.

After Teresa performs her own autopsy, she uncovers some clues to the girl's history that lead her, along with Harm and Mac, to the last place the child lived -- as well as to a recently released convicted child molester.

As Harm considers his future at JAG, he learns that Charlie Lynch -- the ex-Navyman responsible for the murder of Annie, the abused child whose death still haunts Harm -- has resurfaced, placing the little girl's twin sister, Dar-lin, in danger. Putting his career decision on hold until he closes the chapter on Lynch, Harm tracks him to a shipyard where the vicious killer is holding Dar-lin hostage. Overflowing with anger against all Lynch's grisly acts of murder, Harm finds himself in an intense stand-off with him that will leave only one man standing.

Mac becomes upset when Harm tells her at the last minute that he will not be attending her rehearsal duty in order to complete his 6-month required carrier landing qualifications. He assures her that he will be back in time for the wedding. At the church, Chloe is still wary of being friends of Mic. On board the USS Patrick Henry, Harm learns that the LSO who will be grading him thinks of him only as a "land-based Washington weenie." His fears that he won't be graded fairly are realized when he is ordered to land after his first attempt is waved off. After convincing the LSO that they were flying they way that the LSO taught them, he allows Harm to try again. After passing, he then completes his required night traps and requests to head back to Andrews AFB. With an approaching storm, all air operations are suspended, but is assured that he & Skates can be on the first Tomcat, once its forecasted to be safe. With a break in the storm, he & Skates are allowed to go.
