When Harry Potter's name emerges from the Goblet of Fire, he becomes a competitor in a grueling battle for glory among three wizarding schools - the Triwizard Tournament. But since Harry never submitted his name for the Tournament, who did? Now Harry must confront a deadly dragon, fierce water demons and an enchanted maze only to find himself in the cruel grasp of He Who Must Not Be Named. In this fourth film adaptation of J.K. Rowling's Harry Potter series, everything changes as Harry, Ron and Hermione leave childhood forever and take on challenges greater than anything they could have imagined.
