Harry Potter and the Weasleys go to watch the Quidditch World Cup. On that same night, the illegal Dark Mark appears in the sky. When Harry gets back to Hogwarts, he finds out a surprise. The competition between three of the magic schools is taking place this year. This is a very rare event, since it only happens once every five years but hasn't happened for ages because lots of the competitors died. Viktor Krum, a participator in the Triwizard Tournament, is from one of these amazing wizard schools. Hogwarts is the contest's location this year. Even though Harry is not old enough to enter, his name appears inside the magic goblet. He is in. But he soon will learn that the reason he was secretly entered was to put him and the rest of the world in danger.
