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.

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.
