Lance is dating Claire, the school's art teacher, but she doesn't want to get serious or even acknowledge publicly they're dating. In the wake of a freak accident, Lance suffers the worst tragedy -- and greatest opportunity of his life. He is suddenly faced with the possibility of all the fame, fortune and popularity he ever dreamed of; if he can only live with the knowledge of how he got it.
