哈里的父母被杀是因为他们被出卖了，这个天狼星布莱克是否就是那个叛徒呢，波特发现，好友罗恩那只养了12年的宠物耗子竟然是……

After having survived yet another summer with the Dursleys, Harry Potter (Daniel Radcliffe), now 13, joins up with pals Hermione (Emma Watson) and Ron (Rupert Grint) to kick off a new semester at the Hogwarts School of Witchcraft and Wizardry.

But the heartfelt reunion takes a frigid turn on the Hogwarts-bound train when the fab trio has a chilling encounter with the Dementors--morbid phantom guards hired by Azkaban Prison to track down notorious escapee Sirius Black (Gary Oldman).

The wizarding world believes Black is responsible for the deaths of Harry's parents and now wants to murder their only heir. But Harry notices that Sirius Black seems much more interested in Ron's pet rat Scabbers than he is in killing Harry, so the rattled but still curious young wizard decides to track down and confront Black about his parents' death and, in the process, unlocks secrets to his own mysterious past.

Of course, none of this would be possible without the help of Hermione and Ron; Hagrid (Robbie Coltrane), who's now a magical creatures teacher at Hogwarts; and Professor Dumbledore (Michael Gambon), who eradicates pesky obstacles in Harry's way, like linear time constraints.
