Marine gate sentries catch a first-class petty officer with a Stinger missile in the trunk of his car at a fictional submarine base in the Pacific Northwest; officials later find that a second Stinger also is missing. Harm and Meg investigate; at the base they meet Lt. Kate Pike, who was Harm's first partner. While Meg questions the suspect, a brig break takes place, and Meg becomes a hostage. Troops and a chopper pursue the escapees, much shooting follows, and Meg barely avoids drowning. Harm, Meg, and Kate eventually wind up with an armed small satchel-type nuclear weapon; they take it as far as possible from the base before it detonates, and they eventually disarm it.
