In suburban Chicago, Illinois, near the end of the school year, high school senior Ferris Bueller (Matthew Broderick) fakes illness to stay at home. Throughout the film, Ferris frequently breaks the fourth wall to talk about his friends and give the audience advice on various subjects. His parents believe he is really ill, though his sister Jeanie (Jennifer Grey) does not. Dean of Students Edward R. Rooney (Jeffrey Jones) suspects Ferris is a repeat truant and commits to catching him. Ferris convinces his best friend Cameron Frye (Alan Ruck), who is legitimately absent due to illness (though a hypochondriac, which Ferris sees through), to help lure Ferris’ girlfriend Sloane Peterson (Mia Sara) from school on the pretext of a grandmother’s demise. To further the ruse Ferris borrows Cameron’s father’s prized 1961 Ferrari 250 GT California Spyder. Cameron is dismayed when Ferris takes them into downtown Chicago in the car, to spend the day. Ferris promises they will return it as it was.
