It's late 18th century Hampshire and Jane Austen (ANNE HATHAWAY) is a young woman living at home with her parents, Rev. George Austen (JAMES CROMWELL) and Cassandra (JULIE WALTERS), while her brother Henry (JOE ANDERSON) has just returned and taken a liking to Eliza De Feuillide (LUCY COHU), their cousin.
Jane, however, isn't interested in romance and longs to be a writer, something that doesn't sit well with her mother who thinks she should get hitched just like her sister, Cassandra (ANNA MAXWELL MARTIN), who's engaged to be married to a military officer headed abroad.
Mrs. Austen strong encourages Jane to accept being fixed up with Mr. Wisley (LAURENCE FOX), the bland son to the wealthy Lady Gresham (MAGGIE SMITH) who's also in favor of the union. Yet, Jane wants nothing to do with him. However, and after initially disliking him quite a bit, she finds herself drawn to Tom Lefroy (JAMES McAVOY) a dashing and charming young man who desires to be a lawyer and maintains his lifestyle thanks to an allowance from his wealthy uncle, a stern judge who sends his nephew off to stay with Jane's family.
The fact that he's otherwise penniless, however, means that both would likely become paupers should they go against their families' desires and marry. Accordingly, and from that point on, Jane tries to figure out what to do, with her experiences and observations forming the basis of what would later become her highly acclaimed novels about the affairs of the heart.
