Shauna tries to live like a normal 22-year-old, but at 3 feet 10 inches, she's stuck in the body of an 8-year-old. From dating to drinking, she faces surprising obstacles on her quest for independence.

The girls go bridesmaid dress shopping for Tara's wedding, but Shauna gets frustrated when nothing fits her. Wanting to make changes to her life, Shauna considers a future career and joins a gym. Then, Shauna goes on a blind date.

Shauna realises her limitations while getting hands-on experience at a farm. She asks Tara for advice, but things turn sour when they get into an argument. Then, Shauna gets a new tattoo while Mark and Rylee put on their first puppet show in years.

Shauna and Rylee throw Tara a hen do in Pittsburgh that's full of surprises, and things get heated between the sisters while at a bar. Back at home, Mark and Patty enjoy dinner alone and talk about what life will be like as empty nesters.
