The Age of Reason is set in 1938 and tells of Mathieu, a French professor of philosophy who is obsessed with the idea of freedom. As the shadows of the Second World War draw closer - even as his personal life is complicated by his mistress's pregnancy - his search for a way to remain free becomes more and more intense.
