Melinda, who is eight months pregnant, is invited on a cruise ship to be a 'den mother' for four couples. Their task is to find out how the cruise ship is being used to smuggle drugs and money t the different Caribbean islands. It was to be a routine job, to just observe. Halfway through this job, the cruise ship is attacked, and reinforcements are called in. The U.S.S. Enterprise arrived first, and then from Aruba, a secondary group happens to be available. The latter group is unusual, in that all of the men are under five feet tall. Together they were able to solve the smuggling problem and divert an attack from four different cartels on the cruise ship.
