The Good Shepherd (2006)

Matt Damon and Robert De Niro (who also directs) star in this partially fact-based drama that examines the early history of the CIA as seen through the eyes of a dedicated agent. An upstanding, sharp-minded Yale student, Edward Wilson (Damon) is recruited to work for the fledgling CIA during World War II. Though loyal to his country, Wilson begins to feel the job eroding his ideals, filling him with distrust and destroying his personal life.
