Jaminson D. Hutch, archaeology professor, is "somewhere" in the Bahamas. He is in search of the fabled Spanish treasure on board the Nuestra Senora de la Concepion, which was sunk in 1641. It is believed there is a gold horde of more than forty tons below the deck – worth thirty-five million dollars! Join the Penetrator as he combs the Caribbean – on land and sea – fighting modern day pirates – in order to rescue the professor and the buried treasure. If you think Mark Hardin is indestructible on dry ground – he's even more ferocious underwater – and he comes up with more than gold doubloons and pieces of eight.
