Tom, a foundling abandoned at birth, is adopted by the benevolent Squire Allworthy. He grows up and falls desperately in love with Sophia Western, the daughter of the neighbouring squire. Unfortunately for Tom, Sophia is already betrothed to Blifil, his scheming arch-rival.

Tom embarks on a journey, while Sophia attempts to escape the threat of marriage.

Tom's spirited adventures in search of his beloved Sophia bring him into violent confrontations with a press-gang hired by Lord Fellamar and the dangerous Mr Fitzpatrick.
