Plot: After a lonely summer on Privet Drive, Harry returns to a Hogwarts full of ill-fortune. Few of students and parents believe him or Dumbledore that Voldemort is really back. The ministry had decided to step in by appointing a new Defence Against the Dark Arts teacher that proves to be the nastiest person Harry has ever encountered. Harry also can't help stealing glances with the beautiful Cho Chang. To top it off are dreams that Harry can't explain, and a mystery behind something Voldemort is searching for. With these many things Harry begins one of his toughest years at Hogwarts School of Witchcraft and Wizardry.

Plot: Harry's fourth year at Hogwarts is about to start and he is enjoying the summer vacation with his friends. They get the tickets to The Quidditch World Cup Final but after the match is over, people dressed like Lord Voldemort's 'Death Eaters' set a fire to all the visitors' tents, coupled with the appearance of Voldemort's symbol, the 'Dark Mark' in the sky, which causes a frenzy across the magical community. That same year, Hogwarts is hosting 'The Triwizard Tournament', a magical tournament between three well-known schools of magic : Hogwarts, Beauxbatons and Durmstrang. The contestants have to be above the age of 17, and are chosen by a magical object called Goblet of Fire. On the night of selection, however, the Goblet spews out four names instead of the usual three, with Harry unwittingly being selected as the Fourth Champion. Since the magic cannot be reversed, Harry is forced to go with it and brave three exceedingly difficult tasks.

Plot: Forced to spend his summer holidays with his muggle relations, Harry Potter gets a real shock when he gets a surprise visitor: Dobby the house-elf, who warns Harry Potter against returning to Hogwarts, for terrible things are going to happen. Harry decides to ignore Dobby's warning and continues with his pre-arranged schedule. But at Hogwarts, strange and terrible things are indeed happening: Harry is suddenly hearing mysterious voices from inside the walls, muggle-born students are being attacked, and a message scrawled on the wall in blood puts everyone on his/her guard - "The Chamber Of Secrets Has Been Opened. Enemies Of The Heir, Beware" .
