Winter 1908: Elizabeth befriends a bunch of Bohemian-types, but is drawn to two in particular: Evelyn Larkin, a radical Socialist extremist, and her lover, Lawrence Kirbridge, a handsome, free-spirited poet.

On the eve of her 21st birthday, with her parents out of town, Lizzy invites the entire group to Eaton Place, and is humiliated when the Bellamys return home unexpectedly and throw everyone out. Anxious to prove she's nothing like her parents, Lizzy is compelled to do something extreme, leading to a falling out with her parents and a harsh discovery about Evelyn.

June 1909: Elizabeth and Lawrence Kirbridge have fallen in love and, refusing to conform to society's rules, announce their plan to live together without marriage, resulting in pressure from all sides. After Lawrence gives in and starts pressuring her too, Lizzie finally succumbs.

Meanwhile, Sarah fulfills her dream to perform on the stage when she takes a job in a burlesque show. James shows up and, now that she no longer works for his family, wants to pursue the relationship they've both wanted for nearly six years.

Mr. and Mrs. Lawrence Kirbridge return from their honeymoon and set up their new household in nearby Greenwich.

Things have not improved in the Kirbridge household. It turns out they have yet to consummate their marriage. Lizzie, unaware she's married to a gay man, is miserable and angry, making Lawrence miserable, too. Realizing he cannot fulfill that "need" for her, Lawrence decides to enlist the help of a friend to fulfill those duties for him.

Elizabeth comes home for Christmas without Lawrence. The Bellamys face another family crisis when it is discovered that Elizabeth is expecting a baby.

Elizabeth returns home with her newborn daughter, Lucy, and the very disagreeable and old Nanny Webster, to look after "Baby".
