In this play three married couples - The Fosters, The Philips and The Featherstones, attend two dinner parties on consecutive nights. The couples have little in common although, unbeknown to their respective partners, Fiona Foster and Bob Philips are having an affair. Mary & William Featherstone, invited to both parties, have no idea what is happening. Cover-ups and subterfuge become a recipe for confusion and a comedy to remember!
