Crank Wilson and Julia Thompson love each other madly. But after Crank's huge mistake during the summer, on the road with Crank's rock band Morbid Obesity, they aren't getting along. Sean Wilson and Carrie Thompson are the seventeen year old younger siblings of Julia and Crank. Carrie is on her way to New York to start college at Columbia University and Sean is on his way home to Boston. For the next five days, they're stuck in a car. Along the way, they'll contend with screaming matches, giant spiders and a 240-pound pissed off Marine. And the whole way, Crank will be faced with one question. After he screwed up so badly, is there any way he can win Julia back?
