A clerical error leads to the appointment of a left-leaning small-town priest to a rich village, where he immediately horrifies his snobby parishioners by appointing a dustman and a black man as vicar's wardens and throwing open the vicarage to the sprawling, disreputable Smith family, who have just been evicted from their caravan site. He converts the dowager aristocrat to works of absurd charity but he soon has the town and much of the country in uproar.
