Born into a poor family, Fanny Price is raised amid the daunting splendour of Mansfield Park by her rich uncle, Sir Thomas Bertram. Treated as an inferior by most of the family, Fanny forms a close attachment to her cousin Edmund, the only person to show her kindness.

With the departure of her uncle to the West Indies and the arrival from London of the fashionable Henry and Mary Crawford, flirtation and romantic intrigue abound. As Fanny becomes increasingly uncomfortable with the conduct of her companions, she finds herself isolated and forced to face the conflict between her sense of integrity and social expectation.
