Stealing tea cups and saucers from the Titanic wreck site is not an easy task. Doing it without getting your feet wet is even harder. Dexter Knight and his two mismatched partners have managed to do it, but are finding it difficult to turn their acquisitions into cold hard cash. When one such sale goes horribly awry, they wind up hijacked, along with their technology. Unsure if he’s now working for a government agency or a criminal conspiracy, Dexter finds his team dragged out to the oceans deepest spot, the Marianas Trench. There, beneath seven miles of sea water, lies an unknown object far more intriguing than fine china. While Dexter would prefer to get back to civilization and dry land, he finds himself pondering a more ominous question. If he leaves without solving the mystery beneath the waves, will there be any civilization to go back to?
