Determined to reclaim their social standing, Jamille prepares for a high-society garden party, with 8-year-old Nicki mimicking her every "sophisticated" move. The plan for elegance falls apart when Nicki accidentally uses Arthur’s experimental "super-grip" industrial glue to repair Jamille’s heirloom lace fan. By the time they reach the party, the fan is permanently stuck to a serving tray, a local stray cat, and eventually, the host's expensive wig. Meanwhile, Michelle tries to convince the landlord that the "rhythmic banging" coming from the basement is a new modern music trend rather than Arthur’s failing steam-laundry machine.

When a group of local boys claims that "fine ladies" can't handle the new high-wheel velocipedes, Jamille decides to defend the family honor by entering the neighborhood’s first street race. Not wanting to be left behind, 8-year-old Nicki builds a "matching" miniature bike out of old crates and a spinning wheel. As Jamille struggles to stay elegant while pedaling at top speed, Nicki’s chaotic racing style and Arthur’s "rocket-booster" steam attachment turn the race into a city-wide chase. Meanwhile, Michelle tries to win back the family’s silver tea set by betting on the girls to beat the neighborhood bully.

Jamille decides to open a "Finishing School" for the neighborhood children to earn extra money. Nicki joins as the assistant instructor, but her version of "proper tea service" involves a slingshot and a very confused bulldog. The class becomes a hit when the local kids realize Jamille's "graceful movement" lessons are actually great for dodging the police during street games

Arthur enters a race with a car powered by cooking grease. Jamille and Nicki try to act like "Grand Prix" models.

Jamille tries to convince a visiting Duchess she still lives in a mansion. Nicki accidentally reveals the truth by inviting the Duchess to a game of "Street Poker."

Arthur’s new barber-bot goes haywire. Jamille has to hide a terrible haircut with a massive hat, while Nicki tries to start a "Short Hair" trend.

Michelle runs for "Neighborhood Captain." The girls act as her campaign managers, handing out "sophisticated" flyers that are actually just drawings of Jamille.

The family finally reaches the Fair! Jamille gets lost in the Hall of Mirrors, and Nicki uses her "Mini-Me" skills to find her by tracking her sister’s perfume.

The Pringles throw a massive street party. Arthur’s giant fireworks invention nearly takes out the city, but the family realizes they prefer the tenement to the manor.
