Diving the Chesapeake Bay for oysters, former SEAL Ben Blackshaw finds a wrecked speedboat laden with gold, a stolen nuke, and the corpse of a man who's been missing for fifteen years, his father. A psychotic merc, Maynard Chalk, raids Blackshaw's Smith Island home to snatch the blighted cargo. Blackshaw must defend the gold, rescue hostages, and stop the bomb. Failure means World War III.
