Jim Dixon feels anything but lucky. At the university he has to do the bidding of absent-minded and boring Professor Welch to have any hope of keeping his job. Worse, he has managed to get entangled with unexciting but neurotic Margaret Peel, a friend of the Professor's. All-in-all, the pub is the only friendly place to be. His misery is completed at a dreadful weekend gathering of the Welch clan by the arrival of son Bertrand. Not so much that Betrand is loud-mouthed and boorish - which he is - but that he has as companion Christine Callaghan, the sort of marvellous and unattainable woman Jim can only dream about.
