When it comes to getting his way, Ferris Bueller is not far short of a force of nature. Smug, self-centered and thoroughly full of himself, he has his parents, his best friend and most of the student body of his high school wrapped around his little finger. One of the few things that frustrates him is that he doesn't have a car—for reasons unexplained his parents gave one to his younger sister, one of two people who don't buy his act for a second. The other is Mr. Rooney, the high school principal determined to catch Ferris out on his latest caper and yet seems not at all equipped to manage it.
Make no mistake though, this film is not actually about Ferris but about his best friend Cameron, a repressed teen so sunk in hypochondriacal ennui you wonder why he doesn't just wink out of existence. But Ferris, though his main reason for stirring Cameron out of his slough of despond is in order to secure transportation for the day, is not wholly devoid of altruistic feeling. He puts a fair amount of effort into trying to get Cameron to respond to life, first by running a scam on Mr. Rooney and then…well, that's where the adventure begins.
