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...

Harry, Ron and Hermione, now teenagers, return for their third year at Hogwarts. There they are forced to face escaped prisoner, Sirius Black, who poses a great threat to Harry. In addition to new experiences, Harry must overcome the threats of Dementors, outsmart a werewolf and finally deal with the truth about Sirius and his relationship with his parents. Harry and friends master advanced magic classes, cross time barriers and change the course...

An orphaned child that has spent the first ten years of his life living under the stairs of his aunt and uncle's house is invited to join the Hogwarts School of Witchcraft and Wizardry. He learns his destiny lies in the realm of magic and fantasy. Includes the theatrical and extended versions.

Year three at Hogwarts means new fun and challenges as Harry learns the delicate art of approaching a Hippogriff, transforming shape-shifting Boggarts into hilarity and even turning back time. But the term also brings danger: soul-sucking Dementors hover over the school, an ally of the accursed He-Who-Cannot-Be-Named lurks within the castle walls, and fearsome wizard Sirius Black escapes Azkaban.

In the epic finale, the battle between the good and evil forces of the wizarding world escalates into an all-out war. The stakes have never been higher and no one is safe. But it is Harry who may be called upon to make the ultimate sacrifice as he draws closer to the climactic showdown with Lord Voldemort. It all ends here.
