With the future of the wizard world at stake, teenaged wizard Harry Potter enters into his final battle against the evil Lord Voldemort. Potter turns to friends, teachers, and other members of the Order of the Phoenix for help in defeating Voldemort's forces. The discovery of spies within the Order forces Harry and the others to choose their allies carefully.

Part 1 begins as Harry, Ron and Hermione set out on their perilous mission to track down and destroy the secret to Voldemort's immortality and destruction--the Horcruxes. On their own, without the guidance of their professors or the protection of Professor Dumbledore, the three friends must now rely on one another more than ever. But there are Dark Forces in their midst that threaten to tear them apart. Harry's only hope is to find the Horcruxes...

"Till now there's been no magic for Harry Potter. He lives with the miserable Dursleys at number four, Privet Drive. His room is the cupboard under the stairs, and he hasn't had a birthday party in eleven years. But then a mysterious letter arrives by owl messenger: a letter with an invitation to an incredible place called Hogwarts School of Witchcraft and Wizardry. And there he finds not only friends, flying sports on broomsticks, and magic in everything...

When the Chamber of Secrets is opened again at the Hogwarts School of Witchcraft and Wizardry, second-year student Harry Potter finds himself in danger from a dark power that has once more been released on the school.

Harry Potter is mysteriously selected to compete in the prestigious Triwizard Tournament. Meanwhile, supporters of the evil Lord Voldemort send out a shockwave of fear when their Dark Mark scorches the sky, signaling Voldemort's return to power.
