Marc Camoletti's Don't Dress for Dinner

Bernard is planning a weekend with his chic Parisian mistress in a French farmhouse. He has arranged for a cordon bleu cook to prepare gourmet delights, is packing his wife Jacqueline off to her mother's, and has even invited his best friend to provide the alibi. It's foolproof; what could possibly go wrong? Suppose Robert turns up not knowing why he has been invited? Suppose Robert and Jacqueline are secret lovers? What happens if the cook is mistaken for the mistress and the mistress is unable to cook? An evening of hilarious confusion ensues as Bernard and Robert improvise at breakneck speed.
