In mid-1943, at the behest of their Japanese allies, the Germans send their best agent, Johann Schmidt, code name "RAVEN", to sabotage the U.S. Navy's torpedo factory in Newport, Rhode Island. Cunning, intelligent, resourceful, and utterly ruthless, Schmidt arrives off the Rhode Island coast by German U-boat, seemingly undetected. The agent then succeeds in getting on to the Newport Navy Base and finds employment there. This aids Schmidt in discovering the location of the Navy's bulk explosives storage site: Rose Island, located in the middle of the Eastern Passage of Narragansett Bay, one mile west of Newport. However, through cooperation between the British Intelligence Service MI6 and the U.S. Federal Bureau of Investigation (FBI), and aided by a stroke of luck, RAVEN's arrival is discovered. The FBI assigns one of their best counterespionage agents, Brian Weeple, to track down and capture and/or eliminate the saboteur. But Schmidt is not who everyone assumes him to be, significantly complicating the search. Will Schmidt's secret identity be discovered, and can RAVEN be caught and stopped before the assignment is carried out?
