Adapted from the novel by the same author The River Line took the Edinburgh Festival by storm in 1952, where it starred Paul Scofield and Virginia McKenna. In an era before the angry young men of the late fifites, Morgan was considered one of the greatest dramatists of his generation.

Drawing upon his own wartime experience Morgan tells the story of a group of downed, allied pilots in occupied France in 1943 hiding from the Nazis in the granary of a farmhouse owned by a member of the resistance. Tensions rise as they await news of the last leg of their journey through occupied Europe to the Pyrenees along the escape route known as ‘The River Line’. As midnight approaches, one brutal action of terrible suddenness is to haunt their lives forever. It is the story of normal men and women are caught in the turmoil of war and how ordinary people are forced to face up to extraordinary circumstances.
