Casey (short for Acacia, but don't call her that) is spending a few summer days with her parents at Disneyland. Just like they do every summer. Except this summer is different. Casey's best friend has dumped her. She starts high school in the fall, and she's tired of following her parents' rigid schedule and putting up with their embarrassing behavior. She's miserable. Even Disneyland can't make her happy. Then, standing in line for the Indiana Jones Adventure, she bumps into Bert.
