It's the summer before their senior year of high school, and the singing quartet, the Cheetahs, plan to spend the next few months rehearsing. But Chanel (
Adrienne Bailon) learns that she'll be going to Barcelona, Spain. Luckily, the Cheetahs find an ad for an amateur musical competition in Barcelona. Fearless leader Galleria (
Raven-Symone) gets the group an audition, they make the cut, and Galleria's mom agrees to chaperone the trip. But foreign soil provides lots of distractions for the girls, who go their separate ways far too much for Galleria's liking. Recalling that her control-freak tendencies nearly ruined their friendship, she hangs back and waits for them to return for rehearsals. Unfortunately for Galleria, Dorinda (
Sabrina Bryan) has a new love interest; Aquanetta (
Kiely Williams) gets bitten by the fashion bug; and Chanel hits it off with a talented Spanish singer whose mom is bent on breaking up The Cheetah Girls.
