As a reward for winning the school spelling bee, Jo is allowed to host a sleepover at her house, but while planning the party, she cannot figure out why her friends are suddenly acting strangely and keeping secrets from her.
When Kara decides to host the next sleepover, her brothers promise to ruin the party unless she agrees to be their slave, but when Kara's friends discover what is going on, they decide to help Kara get even with her brothers.
Kara has a sleepover to celebrate Thanksgiving and Taylor's soccer team's win, and Jo introduces her friends to her cousin, Ceci, to whom the girls think Jo is paying too much attention.
