It is the story of William Colby, who became Director of the CIA and who was in VietNam at key points in the history of our war there, told by his son.
I recommend that those interested in the history of WWII through the 1996 watch this film. It is especially interesting with regard to the Kennedy era and the use of assassination, surveillance within the US and the abuse of the "Top Secret" designation on documents.
