When Hell Was in Session is a memoir by U.S. Navy Rear Admiral Jeremiah Denton, recounting his experiences as an American prisoner of war (POW) during the Vietnam War. A Navy pilot, Denton's jet was shot down over North Vietnam in July 1965. Denton and his navigator, Bill Tschudy, parachuted down and were soon taken prisoner. Both men spent seven years and seven months in North Vietnam as often-tortured POWs. In 1979, the book was made into a television movie starring Hal Holbrook. It was adapted by screenwriter Jake Justiz, also known as Lee Pogostin.
