"What is so dangerous about a character like Ferris Bueller is he gives good kids bad ideas." The John Hughes '80s classic follows ultra-popular high school senior Ferris Bueller (Matthew Broderick), who decides to call in sick (or, shall we say, barf up a lung?) and go on a downtown Chicago adventure with girlfriend Sloane (Mia Sara) and best bud Cameron (Alan Ruck). But Principal Rooney (Jeffrey Jones) knows that Ferris has to be up to no good, and he leaves school grounds to doggedly pursue Bueller and expose him for the fraud he thinks he is.
