Two pairs of siblings, devotees of Jane Austen, find their lives transformed by a visit to England and Sir Francis Austen, her last surviving brother and keeper of a long-suppressed, secret legacy.
In Boston, 1865, Charlotte and Henrietta Stevenson, daughters of a Massachusetts Supreme Court Justice, have accomplished as much as women are allowed in those days. Chafing against those restrictions and inspired by the works of Jane Austen, they start a secret correspondence with Sir Francis Austen, her last surviving brother, now in his nineties. He sends them an original letter from his sister and invites them to come visit him in England.
