Kylie, Esme, and Lydia, nannies to the stars, rely on their friendship as they face challenges in their work and personal lives and begin their senior year at Bel Air High School.

Working as nannies in Hollywood isn't always easy for friends Esme, who accidentally loses the Goldhagens' twins, Kiley, who works for a drug-using rock star and is trying to figure out if model Tom is her boyfriend or not, and Lydia, who can't seem to make her relationship with Billy move fast enough.
