chunk: In suburban Chicago, high school senior Ferris Bueller fakes sickness to stay home. Ferris frequently breaks the fourth wall, giving the audience advice on how to skip school, and to narrate about his friends. His younger sister Jeannie is less-convinced, but goes to school anyway. Dean of Discipline Edward Rooney notes and suspects Ferris is being truant again and commits to catching him. However, Ferris uses a computer to alter the school's records to indicate his absences from 9 to 2. Ferris convinces his friend Cameron Frye, who is also absent, to report that his girlfriend Sloane Peterson's grandmother has died. Rooney doubts this, but they succeed as planned.
