Popular high school senior Jessica Stone has a secret, she used to be a nerd. But she gave herself the ultimate makeover and applied all her academic genius to study and imitate the social elite and now she rules the school. With her cool new friends and hottest-guy-in-school boyfriend, life's a beach - and that's where she's headed for spring break. That is, until her biology teacher breaks the bad news that she's failing and her only chance to make up the grade is to join the conservation club in Panama to save the golden frog. Jess finds herself in a foreign country with a new social crew, including a ghost from her past that could threaten her queen bee reputation.
