Ferris persuades Cameron to let them use his father's restored 1961 Ferrari 250 GT 'California' to pick up Sloane (as part of their cover) to travel into the city. He sets up an elaborate ruse in his bedroom with a mannequin, a trophy and his stereo in case anyone decides to check on him.
High school senior Ferris Bueller (Matthew Broderick) decides to skip school on a spring day by faking an illness for his parents (Lyman Ward and Cindy Pickett), then encourages his girlfriend, Sloane (Mia Sara), and his pessimistic best friend Cameron (Alan Ruck) to spend the day in Chicago as one of their last flings before they graduate and head off to different colleges.
