September, 1939. On the day England enters World War II, legendary psychoanalyst Dr. Sigmund Freud invites the young, rising Oxford don C.S. Lewis to his home in London. There, only weeks before Freud took his own life, they engage in a brain-teasing battle of wits on the subjects of love, sex, and the existence of God. Filled with humor, this deeply touching play explores the minds, hearts, and souls of two brilliant men addressing the greatest questions of all time.
