Amber and McKenna Williams are the typical mean, rich girls of Califonia. They go to parties almost every week, partying, drinking, and hooking up with the most guys as possible. But, when their cousin, Juliet's parents die in a terrible accident, the two girls have to watch over her while she stays with them. Now, Juliet is not like her mean girl cousins. She is shy, quiet, and insecure. On top of that, she is the youngest female billionaire, another reason for Amber and McKenna to hate her guts.
