When Brian takes up jogging, his wife Hilary is overjoyed. But, instead of jogging, Brian is in fact spending a couple of hours with his girlfriend, Wendy, in his good friend George’s flat. This arrangement works wonderfully for some time; for, while Brian is with Wendy, George knows there is no danger of his being caught at Brian’s flat with Brian’s wife, Hilary! The good times come to an abrupt end, however, when George’s wife Jessica arrives home a day early from the United States and finds her flat occupied by Brian and Wendy. Thinking fast, Brian claims that Wendy is just a Red Cross nurse who rescued him from a jogging accident, but Jessica is still suspicious. This is modern British farce at its hilarious best and a sure guarantee of a delightful evening in the theatre.
