For the non-Rowling devotees, the Goblet of Fire goes something like this: the Triwizard Tournament has come to Hogwarts. It's a centennial magical sports day between competing wizard schools and Harry has been set up to take part in the perilous set of events - you know, dragon baiting, underwater rescues, a deadly maze. The series of challenges will trap him in a confrontation with his dread nemesis, Lord Voldemort (Ralph Fiennes, in his first Potter, transmogrified into a cackling, half-dead ghoul).
