Harry Potter 7 : The Deathly Hallows (Part 1)

Harry Potter and his allies from Hogwarts, the Order of the Phoenix, know that their only hope is to find and destroy the Horcruxes before their enemy the evil wizard Voldemort restores his full powers by killing Harry. By a magical subterfuge they smuggle Harry to The Burrow, the home of the Weasleys, which is secure from magical attack.

At the same time Harry's former schoolmaster Severus Snape, who killed the headmaster Albus Dumbledore, meets with his fellow Death Eaters. He was a double agent within Hogwarts and is welcomed by the revitalized Voldemort and the others.

After escaping a death eater attack on Bill and Fleur's wedding, Harry, Ron, and Hermoine take refuge at 12, Grimmauld Place where they find Kreacher hiding and learn the true identity of RAB as Regulus Black. Harry and his friends find out the true locket of Salazar Slytherin is in the Ministry of Magic. They break into the Ministry, retrieve the locket, and travel magically to a forest. Their attempts to destroy this Horcrux fail, so they take turns wearing it in an attempt to dilute its effects; this quickly drives them to mutual suspicion and fear, as whenever the wearer wears the locket, it causes their paranoia, anger, and stess to rise, especially for Ron. Overcome by suspicion, Ron departs from the group, which leaves Hermione distraught. One evening, while listening to music, Harry invites Hermione to dance with him, and their dance eventually relieves some of their tension and raises their spirits.

Harry and Hermione try to find Bathilda Bagshot, a magical historian who they think will be able to help them, but they are attacked by Lord Voldemort's snake Nagini who has killed her. In the escape from Nagini, Harry's wand is broken. Hermione identifies a young man seen in a vision by Harry as one Gellert Grindelwald.

Following a mysterious doe Patronus, Harry finds the Sword of Gryffindor at the bottom of a frozen pond; this is vital because it can destroy Horcruxes, for it is made to absorb things that only make it stonger, and since Harry used it in his second year at Hogwarts, to kill the basilisk, which lived in the school's Chamber of Secrets, it is now infused with basilisk venom, one of the few things that can destroy Horcruxes. As Harry swims to reach it, the locket attempts to drown him. Ron reappears, saves him, and grabs the sword. Harry convinces Ron to try to destroy the locket. It manipulates Ron's worst fears, but Ron successfully destroys it with the sword.

They visit the Lovegood house, where Xenophilius Lovegood teaches them about the Deathly Hallows, three powerful magical artifacts consisting of; the Elder Wand, reputed to be unbeatable, the Resurrection Stone, which can bring back the spirits of the dead, and the Invisibility Cloak, which renders its wearer undetectable. When they attempt to leave, he betrays them to the Death Eaters as ransom for his daughter Luna. The trio escape and travel magically back to the forest, where a group of Snatchers is waiting. After a chase through the forest they are surrounded. Hermione magically disfigures Harry's face to conceal his identity from the Snatchers. Harry has another vision and sees Voldemort finding Grindelwald. Grindelwald tells him that as a result of their long ago duel, Dumbledore became the master of the Elder Wand.

At Malfoy Manor, Bellatrix imprisons Harry and Ron in the cellar, where she has also imprisoned Luna, the wandmaker Ollivander, and the goblin Griphook; meanwhile, Bellatrix tortures Hermione to try to find out how they acquired the Sword of Gryffindor, which she had believed to be safe in her bank vault.

Harry, using a magical mirror his godfather Sirius gave him, sees another man's face looking back at him. He begs the person in the mirror for help. Dobby then appears and at Harry's request, rescues Luna and Ollivander and returns to help Harry, Ron, Hermione and Griphook. The group rescue Hermione with Dobby's help, but Bellatrix kills Dobby with a dagger as they disapparate. Harry gives Dobby a proper burial on the beach. Later, Voldemort opens Dumbledore's tomb and takes the Elder Wand, casting a powerful curse into the sky.
