 The frigate USS Stanley Dace under the command of Captain Berroa is patrolling the waters of the Caribbean Sea off Cuba when they spot a refugee struggling to stay afloat in the water. To pick her up the ship must cross into Cuban waters. When they do they are intercepted by a Cuban vessel which demands that they turn the girl over to them. Captain Berroa is a Cuban-American who despises Castro s regime and refuses to turn her over. Harm and Bud are sent to the ship to mediate the dispute and try to avoid an international incident.
