Leo Caraway, president of the Young Republicans club, future Harvard student, has his life all mapped out. That is, until he discovers his biological father is the notorious King Maggot, the lad singer of Purge, the most popular and destructive punk rock band in history.
Not only is Leo not a punk rock fan, but he believes the Maggot blood in his veins is a dangerous time bomb just waiting to explode. And sure enough it does - when Leo stubbornly defends the unlikeliest of people, thereby getting himself falsely accused of cheating on a test.
Because of the blemish on his record, the once-star pupil finds his scholarship to Harvard taken away. So he accepts a job as a roadie with Purge's summer revival tour, all the while secretly hoping to convince Maggot to pay for his tuition. But life on the road is even crazier than Leo bargained for, and before the summer is out, he will finally discover the surprising truth about his dad, his friends, and most important, himself.
