Katie tries to fit in with the other Westport moms in order to get Anna-Kat invited to a popular girl's birthday party. When Anna-Kat still isn't invited, Katie vents to Angela and Doris, and realizes her daughter doesn't need a bunch of friends, just a couple of close ones. Elsewhere, Greg tries to convince Taylor that she can't get by on her athletic ability alone, while Oliver complains about a flawed polo shirt that his mom bought at an outlet store.

Anna-Kat tells her parents that all she wants for her birthday is to walk to the library alone.

Katie has been avoiding the mandatory volunteer hours at her kids’ schools all year. But when the other moms pressure her, she hits on a genius excuse after wearing a fake pregnancy “empathy” bump leads everyone to think she is pregnant.

Katie’s efforts to get more time for herself backfire when she is forced to mend fences with the Westport moms by volunteering to run the school’s spring gala. Meanwhile, Oliver proves to Katie that his passion for ballet is genuine, inspiring her to confront his belittling teacher and stick up for him. Taylor and Greg disagree over whether or not she needs to go to college while he teaches her how to drive.

Katie struggles with Taylor and Anna-Kat’s defiance, as Anna-Kat decides she’s now a vegetarian (under the influence of Tara Summers) and Taylor dies her hair blonde without Katie’s permission. Greg and Katie help Oliver come to terms with embarrassment after Oliver has a humiliating moment in ballet class.

After failing to get donations on her own terms, Katie gives in to the dark side and teams up with Oliver to bribe rich Westport families to donate big-ticket items for the spring gala. Greg decides to take Taylor and Anna-Kat to a Revolutionary War reenactment which Taylor finds lame until she starts a revolution of her own.

In order to impress the other moms at school, Katie, Taylor and Oliver travel to New York to track down Nathan Fillion at a "Firefly" convention, so Katie can convince him to attend the school's spring gala.

When things start to fall apart at the last minute, Katie figures out a new way to make the spring gala a success. Meanwhile, Greg attempts to be a "fun dad" and winds up adopting a dog while Katie is occupied with the gala.

Katie lands the perfect pawn to play on the insecurities of the Westport housewives when she convinces a hot young trophy wife named Harper to volunteer as room mom for Anna-Kat’s class, but she quickly shifts gears when Harper rejects Anna-Kat’s idea for movie night. Meanwhile, Greg enlists the help of the kids to get Katie’s mom, Kathryn, to take an interest in someone other than herself.

While Greg enlists Oliver and Anna-Kat’s help to drum up new recruits for the Westport Historical Guild, Katie does her best to support Taylor’s dreams of becoming the next American Idol.

Katie goes to great lengths to appease Principal Ablin in order to ensure Taylor graduates high school. Meanwhile, Greg finishes ghost writing the final chapter of Lonnie's book.
