When Harm and Mac investigate an international incident on a nuclear submarine, their relationship is tested by the cramped quarters.

A transvestite is murdered; a surgeon is knifed outside a hospital; Tony Rodriguez takes the stand in Capt. Fraker's trial.

Mac can no longer hide her powerful feelings for Harm when she gets word that his plane may have disappeared on the very night she is celebrating her impending marriage to Mic.

Mac's wedding party awaits news from the rescue carrier about the search for Harm.
