When four unlikely friends leave during the middle of their high school graduation ceremony, to say that all hell breaks loose would be an understatement. Meet Emma, the valedictorian for their graduating class, whose parents were killed in a car accident her sophomore year and now lives with her older brother who dropped out of college in order to be her legal guardian; Phoenix, a troublemaker who has no plans for college, named after the casino her alcoholic mother suspects she was banged by her father; Jackie, the quiet one of the group who always seems to be drawing in that sketchbook of hers, her purple hair never in anything other than a bun; and finally, Sarah, the only one of the four with her license and a boyfriend--but when her world comes crashing down the day it was supposed to finally start, the only reasonable solution is this: four girls, one car, 2,863 dollars in cash, and a map. What could go wrong?
