The distinguished country gentleman Allworthy, who lives in Somersetshire with his unmarried sister Bridget Allworthy, arrives home from a trip to London to discover a baby boy in is bed. Allworthy undertakes to uncover the mother and father of this foundling, and finds local woman Jenny Jones and her tutor, Mr. Partridge, guilty. Allworthy sends Jenny away from the county, and the poverty-stricken Partridge leaves of his own accord. In spite of the criticism of the parish, Allworthy decides to bring up the boy. Soon after, Bridget marries Captain Blifil, a visitor at Allworthy's estate, and gives birth to a son of her own, named Blifil. Captain Blifil regards Tom Jones with jealousy, since he wishes his son to inherit all of Allworthy possessions. While meditating on money matters, Captain Blifil falls dead of an apoplexy.
