A motorist picks up to escaped convicts. Instead of turning them over to the police he hires them to kill his wife.

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.
