After accepting the role of a chauffeur in a movie, Desmond advises Robert to enhance his abilities. As he can't drive he is already at a disadvantage but when he is asked to do abseiling and scuba-diving as well, he puts his life in danger for the sake of his art...

There are thirty minutes to "curtain up" and backstage Robert is preparing for his first West End lead. When Sue, Desmond and Desmond's wife, Marjorie, come to wish him luck, confusion abounds. Desmond has worse stage fright than his client and somehow manages to lead everyone to believe he is to become a father at 54 - but who is the mother?
