The Vicar – Dr. Charles Primrose – lives an idyllic life in a country parish with his wife Deborah, son George, daughters Olivia and Sophia, and three other children. He is wealthy due to investing an inheritance he received from a deceased relative, and he donates the £35 that his job pays annually to local orphans and war veterans. On the evening of George's wedding to wealthy Arabella Wilmot, the Vicar loses all his money through the bankruptcy of his merchant investor who has left town abruptly.

The wedding is called off by Arabella's father, who is known for his prudence with money. George, who was educated at Oxford and is old enough to be considered an adult, is sent away to town. The rest of the family move to a new and more humble parish on the land of Squire Thornhill, who is known to be a womanizer. On the way, they hear about the dubious reputation of their new landlord. Also, references are made to the squire's uncle Sir William Thornhill, who is known throughout the country for his worthiness and generosity.
