DVD - Harry Potter and the Prisoner of Azkaban

In the summer before his third year at Hogwarts, Harry Potter has had enough of his horrible aunt and uncle, and after accidentally inflating his visiting aunt Marge, he runs away. Unfortunately, there's much more danger in the wizarding world than Harry could ever have imagined; convicted mass murderer, Sirius Black, has escaped from Azkaban, the wizarding prison. Black is known as Lord Voldemort's most devoted follower, and he's after Harry to avenge Voldemort and finish the job. But not everything is what it seems, and inside of Hogwarts there may be a traitor.
