Chatterton and Kohler team up to dive on a sunken U-Boat. They are not friends. Actually, they hardly like each other because they come from different Diver Teams. But one thing they find mutually interesting is figuring out what U-Boat they have found just 60 miles off the coast of New Jersey. They have nicknamed the boat the U-Who because they cannot seem to find any markings on or in the vessel. As Chatterton and Kohler become closer friends they are getting no closer to figuring out the mysterious boat. They scour US Naval records, solicit information from living Germans, and read almost every book they can get their hands on about U-Boats. They learn lots of information about the manufacturing of U-Boats, where they were sent, and who commanded them. They were finally able to find out which U-boat the U-Who was, but not until after years of research and the loss of life.
