1994. While diving off the coast of Jekyll Island, Georgia, retired FBI agent, Neal Park, finds a rusty, metal box wedged between two large rocks. The contents of the box, marked with a Nazi swastika and a German officer's name, take him on a search to England and Germany for the intended recipient of the box's contents. **********1939. From Sudbury, Suffolk County, England, Cynthia Stiles and Margaret Overstreet, bestfriends since childhood, and now on holiday with their families at the Ostee Resort on the Baltic seacoast of northeast Germany, meet Gerhardt Prien, son of a farmer, as he finishes delivering fresh vegetables from the farm in Schmiedekamp, north of the resort. They speak for a few minutes and he asks if they will join him that evening at the lodge dance.
