Harry Potter (Daniel Radcliffe) has turned 13 when his Aunt Marge (Pam Ferris), comes to visit. Harry has never gotten along well with Aunt Marge and after being pushed by her, he causes her to inflate like a balloon and blow away into the sky. The Ministry of Magic strictly forbids students from using magic outside of their world so Harry flees his relatives home, to avoid punishment. Harry joins up for another year at Hogwarts, school of magic run by Albus Dumbledore (Michael Gambon).
Sirius Black (Gary Oldman), has escaped from the Azkaban prison after 12 years behind bars. It's rumored that Black has returned to seek revenge on Harry for rendering the dark wizard Voldemort powerless. Voldemort was Black's master and he is determined to do away with Harry, who's merely a boy. When Harry learns Black is close he has serious fainting spells that render him worthless. The Defense Against the Dark Arts professor Remus Lupin (David Thewlis), and his friends Ron Weasley (Rupert Grint) and Hermione Granger (Emma Watson) help Harry determine what the clues mean to help Harry learn his past.
