London, 1937. Mrs Laura Henderson, a woman of wealth and connections. has just buried her beloved husband. And now she's bored. At 69, she is far too energetic and vital to fade into gentle widowhood. What she needs, say her friend Lady Conway, is a hobby. Collecting diamonds, perhaps? Or doing charitable works? But, to the shock of her friends she instead buys a theatre - the Windmill Theatre in the heart of Soho.
