Rufus Scrimgeour gives a speech to the Ministry stating that it has and will always stay strong through these "dark times." Severus Snape, now the Headmaster of Hogwarts, meets with Voldemort and his fellow Death Eaters at Malfoy Manor where he then shares his intelligence about when Harry will be moved from his home. Harry Potter and his friends Ron Weasley and Hermione Granger know that their only hope is to find and destroy the Horcruxes before their enemy Voldemort restores his full powers by killing Harry. Voldemort is forced to borrow a wand since his is unable to kill Harry. The Order and Harry's friends show up at the Dursleys' house and turn all of his friends into decoys of Harry to move him to The Burrow, the home of the Weasleys. Once they're in the sky, they are immediately attacked by Death Eaters. Voldemort's borrowed wand fails to kill Harry, whose wand acts of its own accord. Mad-Eye Moody and Harry's owl, Hedwig, are killed during the battle. Despite the deaths during the attack, they manage to make it to the Burrow.
At the Burrow, The Minister of Magic, Rufus Scrimgeour, arrives and distributes the items from Dumbledore's last will and testament: the Deluminator to Ron, his personal copy of "The Tales of Beedle the Bard" to Hermione, and to Harry, the Snitch Harry caught in his first Quidditch game. Dumbledore also bequeathed Godric Gryffindor's sword to Harry, but Scrimgeour maintains that the Sword was not Dumbledore's to give. Also, the whereabouts of the Sword are unknown. Later, the wedding of Bill Weasley and Fleur Delacour is interrupted by Death Eaters. During the chaos, Ron, Harry and Hermione disapparate to London, where they are attacked again by two Death Eaters in disguise in a cafe. While planning not to return for their final year at Hogwarts, they head to #12 Grimmauld Place, where the house-elf Kreacher is hiding. They discover that RAB is Regulus Arcturus Black and that Mundungus Fletcher has stolen the real locket of Salazar Slytherin from the house. Harry orders Kreacher to apprehend Mundungus, who reveals that the locket is in the possession of Dolores Umbridge. Using Polyjuice Potion, the trio break into the Ministry, retrieve the locket, and Disapparate to a forest.
Despite their attempts, they are unable to destroy the Horcrux, which makes its bearer experience deeply negative thoughts. They take turns wearing it in order to dilute its effects. Especially susceptible to its effects, Ron is overcome by suspicion that Harry and Hermione are getting close and departs from the group. His departure, combined with the tension of their situation, is a severe blow to their morale. Harry momentarily raises their spirits when he invites Hermione to dance with him as they listen to some music on Ron's radio. Harry sees a vision of Voldemort interrogating and killing Gregorovitch, an old wand-maker, and going off in search of a mysterious teenage wizard that Gregorovitch said robbed his shop many years ago.
Harry and Hermione go to Godric's Hollow to find Bathilda Bagshot, a magical historian who they think may have the Sword, which they have determined can destroy Horcruxes as it is impregnated with Basilisk venom, but they are nearly cornered by Lord Voldemort's snake Nagini who has killed her. Hermione identifies the teenage wizard seen in Harry's vision as Gellert Grindelwald.
Harry sees a Patronus doe, follows it to a frozen pond, and finds the Sword of Gryffindor. As Harry swims to reach it, the locket attempts to drown him, but Ron reappears and saves him. Harry convinces Ron to try and destroy the locket with the sword. It manipulates Ron's worst fears, but Ron successfully destroys it with the sword.
After seeing a strange symbol throughout their journey, they decide to visit someone who knows what significance the symbol has. Xenophilius Lovegood teaches them about the Deathly Hallows (an invincible Elder Wand, a Resurrecting Stone, and an Invisibility Cloak). Together all three items make someone a "master of death." Xenophilius betrays them to the Death Eaters as ransom for his daughter Luna. The trio escape and Disapparate back to the forest, where a group of Snatchers are waiting to capture them and take them to Malfoy Manor. Harry, meanwhile, has another vision and sees Voldemort finding Grindelwald who tells Voldemort that as a result of a long ago duel, Dumbledore is now the master of one of the Deathly Hallows, 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 (by carving the word "mudblood" into her arm) to try to find out how they acquired the Sword of Gryffindor, which she had believed to be safe in her bank at Gringotts.
Harry, using a magical mirror, sees what he believes to be the face of Dumbledore and 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. During the rescue, Bellatrix kills Dobby as they Disapparate. Harry gives Dobby a proper burial on the beach. The first part closes with Voldemort breaking Dumbledore's tomb, stealing the Elder Wand and testing it's power.
