The team retrieve a mangled letter addressed 'To Whom It May Concern.' Their investigation hits a road block with an old postmark and a government form for the U.S. Army Office. The accompanying letter from a young woman describes her search for a soldier who saved her life and helped her escape Afghanistan during the war. When they discover the Army officer has gone off the grid, Supervisor Theresa Capodiamonte challenges them to find the intended recipient, even if he doesn't want to be found.
