Alan Ayckbourn's play follows three married couples whose lives are hopelessly entwined. Frank employs Bob and William and is considering William for promotion. Bob is having an affair with boss Frank's wife Fiona and argues constantly with his own wife, Teresa.
When Frank gets the wrong end of the stick and Bob’s wife Theresa tries to be helpful, misunderstandings abound which result in two dinner parties (held on two different nights) being served simultaneously: but that complication only adds to the fun of this famous farce.
