I am afraid I can not go into too much detail as the movie counts on surprise and anticipation.
Three high school comrades Ferris Bueller (Mattew Brodrick), Cameron Frye (Alan Ruck), and Sloane Peterson (Mia Sara) take the day off. They have several adventures which take them to many fun locations among which are a parade, restaurant, and just skirt being detected. Even though this is a teenage fantasy everyone can enjoy it.
Ben Stein gives the performance of his life as the enthusiastic economics teacher. "Anybody...anybody?"
Meanwhile the principal Ed Rooney (Jeffrey Jones), which knows of Ferris' devious ways, investigates and is foiled at every turn.
Ferris' jealous sister Jeanie (Jennifer Grey) has a few adventures of her own which include meeting a boy in the police station (Charlie Sheen.) She eventually comes to appreciate Ferris' ways.
Naive parents Katie (Cindy Pickett) and Tom (Lyman Ward) move blissfully through the movie only wanting what is best for their under the weather son.
For those musically inclined the movie is packed with great tunes.
Want a gummy bear Mr. Rooney?
