Dumbledore and Harry Potter learn more about Voldemort's past and his rise to power. Meanwhile, Harry stumbles upon an old potions textbook belonging to a person calling himself the Half-Blood Prince.
As Death Eaters wreak havoc in both Muggle and Wizard worlds, Hogwarts is no longer a safe haven for students. Though Harry (Daniel Radcliffe) suspects there are new dangers lurking within the castle walls, Dumbledore is more intent than ever on preparing the young wizard for the final battle with Voldemort. Meanwhile, teenage hormones run rampant through Hogwarts, presenting a different sort of danger. Love may be in the air, but tragedy looms, and Hogwarts may never be the same again.
