Harry Potter and the Goblet of Fire

During the summer, there is an attack at the Quidditch World Cup. The cloaked assailants resemble Death Eaters, the followers of Voldemort. When the school term begins at Hogwarts, Alastor "Mad-Eye" Moody is introduced as the new Defence Against the Dark Arts professor. Dumbledore announces that students from the foreign wizarding schools Beauxbatons and Durmstraang will be arriving at Hogwarts to participate in the Triwizard Tournament. Students who meet the age requirement are invited to enter themselves in the tournament by putting their names into an artefact called the Goblet of Fire. Although Harry does not nominate himself, he is mysteriously selected to compete against the older students Cedric Diggory, Fleur Delacour and Viktor Krum.
Harry is interviewed by the Daily Prophet reporter Rita Skeeter, who writes a scathing article portraying him as a disturbed attention-seeker. Using the Hogwarts Floo Network, Harry speaks with his godfather Sirius Black, who warns him about Durmstrang's headmaster Igor Karkaroff, who is a former Death Eater. Sirius believes that Harry's selection for the dangerous tournament is somehow connected to the attack at the World Cup. Hagrid alerts Harry that the First Task involves a dragon. After Moody reminds Harry that he is an expert flyer, Harry uses his broomstick to fly past the dragon and accomplish the task.
As Christmas approaches, Harry asks a girl named Cho Chang to the Yule Ball, but she is already going with Cedric. Harry and Ron end up going to the ball with the twin sisters Parvati and Padma Patil. Ron is sullen as he observes Hermione dancing with Krum. As the Second Task nears, Harry learns that he will need to rescue someone from the lake. The house-elf Dobby gives him Gillyweed, which allows him to breathe underwater long enough to rescue both Ron and Fleur's sister Gabrielle. He is awarded extra points for his bravery and is tied for first place.
In the Third Task, Harry and his competitors must navigate a maze of obstacles to reach the Triwizard Cup. Harry and Cedric reach the Cup at the same time and decide to grab it together. They are immediately transported to a graveyard, where Peter Pettigrew kills Cedric and subdues Harry. Using Harry's blood, he performs a rite that returns Voldemort to bodily form. As Voldemort and Harry duel, their wands magically connect. This distraction allows Harry the chance to escape back to Hogwarts with the Cup and Cedric's body.
Dumbledore, McGonagall, and Snape discover that Moody is actually the Death Eater Barty Crouch Jr, who has been constantly drinking Polyjuice Potion. When they administer him a truth potion, he reveals that he placed Harry's name in the Goblet, supported him through the Tasks so that he would reach the Triwizard Cup first, and ensured he was transported to the graveyard for the rite by turning the cup into a Portkey. Crouch Jr. is handed over to the Dementors, who render him soulless with the Dementor's Kiss. Recovering in the hospital wing, Harry narrates the events to Cedric's parents and offers them his tournament winnings; they will not accept the gold, so he gives it to Fred and George Weasley so they can open their joke shop. During a memorial service for Cedric, Dumbledore tells the students of Hogwarts that Voldemort has returned. Cornelius Fudge, the Minister of Magic, is sceptical of Harry's story.
