Set in London, Kathryn Miles's marriage is threatened when she discovers her husband's longstanding affair with her best friend but surprises everyone when she uses it to create a new life for herself.

Based on the 1926 play 'The Constant Wife' by W. Somerset Maugham, this comedy takes a modern and amusing take on marriage and infidelity and gives a quick-witted, alternative view on how to deal with an extramarital affair and has a surprising feminist and forward outcome.—mahajanssen
