Harry Potter and the Deathly Hallows – Part 2
Harry, Ron and Hermione seek help from a goblin named Griphook, who helps them sneak into a magical bank. The trio break into Bellatrix Lestrange's bank vault and steal a cup which is a Horcrux (an object that Lord Voldemort has put part of his soul inside). They also soon figure out that another Horcrux, a diadem, is located in Hogwarts.
