The film follows high school senior Ferris Bueller (Matthew Broderick), who decides to skip school and spend the day in downtown Chicago. Accompanied by his girlfriend Sloane Peterson (Mia Sara) and his best friend Cameron Frye (Alan Ruck), he creatively avoids his school's Dean of Students Edward Rooney (Jeffrey Jones), his resentful sister Jeanie (Jennifer Grey), and his parents. During the film, Bueller frequently breaks the fourth wall by speaking directly to the camera to explain to the audience his thoughts and techniques.
