"A teen prankster must make it through his senior year without receiving a demerit in order to claim his $10,000 inheritance. When one of his pranks puts the real principal in the hospital, he enlists the aid of a drifter to take the principal's place."@en
"Teenage prankster John Scaduto (Bryan) is challenged by his parents: not one demerit during his senior semester or he will lose a $10,000 inheritance from his grandmother. The term begins with a demerit as he undermines his unpopular principal and then, accidentally, sends him on an unscheduled sabbatical-- to a mental institution! This clears the way for his grandest prank of all: recruiting an imposter to pose as the principal and erase the demerit."
