-As Lord Voldemort retrieves the Elder Wand from Albus Dumbledore's tomb, Professor Severus snape has become the new headmaster of Hogwarts. Meanwhile, after burying Dobby, Harry Potter speaks with the goblin Griphook about breaking into Bellatrix Lestrange's vault at Gringotts bank, suspecting a Horcrux may be hidden there. Griphook agrees to take Harry, Ron and Hermione to the vault in exchange for the Sword of Gryffindor. Harry asks Ollivander, the wand maker, to ID 2 wands from Malfoy Manor. Ollivander says that they belonged to Bellatrix and Draco, but Malfoy has changed his allegiance to a different wand.
-From a single strand of hair from Bellatrix's clothes, Hermione uses polyjuice potion in order to disguise herself as Bellatrix to break into the Lestrange's vault at Gringotts. She uses the wand Harry obtained from Malfoy and alters Ron's appearance while Harry and Griphook hide under Harry's invisibility cloak. In Bellatrix's vault, Harry discovers that the Horcrux is Helga Hufflepuff's cup. He obtains it but Griphook takes the sword and leaves them, cornered by security. The trio release the dragon there and escape. Harry has a vision of Voldemort furiously killing goblins, including Griphook, and learns he has discovered the theft. Harry also learns that there is a Horcrux at Hogwarts, that it is in some way related to Rowena Ravenclaw. The trio apparate to Hogsmeade, which sets off alarms. They are rescued by Aberforth Dumbledore, who instructs a portrait of his sister, Ariana, to fetch Neville Longbottom. He leads them to a secret passageway that leads into Hogwarts. In the Room of Requirement, they are reunited with Dumbledore's Army and request their help to find Rowena Ravenclaw's diadem.
-Snape hears of Harry's return to Hogwarts and informs staff and students of the severe punishment for aiding Harry. He confronts Snape about Dumbledore's death and Minerva McGonagall challenges Snape to a duel. He flees and McGonagall gathers the community of Hogwarts to prepare for battle. At Luna Lovegood's insistence, Harry speaks to Helena Ravenclaw's ghost. She reveals that Voldemort's performed "dark magic" on her mother's diadem, which is in the Room of Requirement. Ron and Hermione go to the Chamber of Secrets, where Hermione destroys Helga Hufflepuff's cup with a Basilisk fang, after which Ron and Hermione kiss. In the Room of Requirement, Draco Malfoy, Gregory Goyle, Blaise Zabini attack Harry, but Ron and Hermione intervene. Goyle casts a Fiendfyre curse but falls to his death instead. However Malfoy and Blaise are saved by the trio before destroying the diadem. As the school is attacked by Voldemort's forces, Harry, again looks into Voldemort's mind, to locate him and the snake Nagini, which is the final Horcrux. After entering the boathouse, the trio witness Voldemort telling Snape that since Dumbledore was the Elder Wand's previous owner and Snape killed Dumbledore, the Elder Wand can't properly serve him until Snape dies, and has Nagini murder Snape. Before dying, Snape tells Harry to take his memories to the Pensieve. Fred, Lupin, Tonks, and Lavender are killed in the battle
-From watching Snape's memories, Harry learns that Snape was a childhood friend of his mother Lily at a young age, and that he loved her his whole life. Following her death, Snape agreed with Dumbledore to protect Harry from Voldemort out of his love for Lily. Harry also learns that Dumbledore's death at Snape's hands was planned between them. Harry became a Horcrux when Voldemort originally failed to kill him and he must die in order to destroy the piece of Voldemort's soul within him
-Harry goes to die at the hands of Voldemort in the Forbidden Forest, after being comforted by the appearance of his parents, Sirius, and Remus from the Resurrection Stone which was hidden in the Golden Snitch. Voldemort casts the Killing Curse upon Harry, who finds himself in a strange world where Dumbledore's spirit meets him and explains that the part of Voldemort within him was killed by Voldemort's curse and that "Help will always be given at Hogwarts to those who deserve it." Harry decides to return to his body to face Voldemort for the final time.
- Voldemort announces Harry's death to everyone at Hogwarts, and that everyone who defies him will be killed. As Neville gives a speech, Harry reveals that he is alive. Neville draws forth the Sword of Gryffindor from the Sorting Hat, and as Harry and Voldemort duel in the courtyard, Neville decapitates Nagini, rendering Voldemort mortal. Molly Weasley kills Bellatrix in the Great Hall after Bellatrix attempts to kill Ginny and avenges the death of Sirius, Tonks and Dobby. Voldemort casts his final Killing Curse at Harry, but his curse rebounds and kills Voldemort once and for all. Harry is joined by Hermione and Ron, and he explains that the Elder Wand had recognised him as the master because he disarmed Draco at Malfoy Manor who in turn had disarmed it's previous owner, Dumbledore. Harry snaps the wand in half, rejecting it's power.
-19 years later, Harry and Ginny Potter, along with Ron and Hermione Weasley, watch proudly as their children leave for Hogwarts
