Join twins Mia and Maddie and their sidekick little sister, LuLu, as they travel the country with their famous mother, singer Gloria Glimmer, and their slightly wacky nanny Miss Twist. The sisters learn lessons about being good friends, telling the truth, and a whole lot more along the way. A stop in San Diego might be just the break the girls need-lovely weather and great sights to see. That is until they hear animal handlers at Watery World talking about the trouble they've been having keeping the animals in their habitats. Mia and her sisters cannot resist a challenge, talking Miss Twist into another visit to the educational amusement park to search for clues as to what or who is helping the animals escape.
