“Harry Potter and the Prisoner of Azkaban” is the third novel in J.K. Rowling’s Harry Potter series, and the third movie installment. The story begins during Harry’s summer vacation with his Muggle (non-magical) relatives, the Dursleys. Harry is having a rough time at their home in Privet Drive because they treat him poorly and don’t understand his magical abilities. He feels lonely and isolated, but when he is attacked by Dementors, dark creatures sent by the Ministry of Magic to protect against escaped prisoner Sirius Black, he realizes the gravity of the situation.

Harry, Ron, and Hermione are back for another year at Hogwarts School of Witchcraft and Wizardry. This year, though, things are different. A notorious prisoner named Sirius Black has escaped from the wizarding prison, Azkaban, and is believed to be after Harry. Dementors have been sent to guard the school, and their presence is affecting even the strongest wizards, causing them to relive their worst memories.

Harry, Ron, and Hermione succeed in dissipating the dementors. During the school year, they learn that Sirius Black is not the bad guy everyone thinks he is. Black was framed for the murder of Harry’s parents, but it was actually Peter Pettigrew, a former Hogwarts classmate, who betrayed them. Pettigrew is hiding in plain sight at Hogwarts, disguised as a pet rat belonging to Ron’s younger sister, Ginny.

At the end of the school year, Harry, Ron, and Hermione finally come face-to-face with Pettigrew, who transforms into a rat and escapes. Sirius and Remus Lupin, who was once a friend and classmate of Harry’s parents, reveal to Harry the truth about his parents’ deaths. Black persuades Harry to live with him, having escaped conviction and vowing to protect Harry.

In the final moments, Harry and Hermione use a powerful time-turner to go back in time and save Buckbeak, a hippogriff who was sentenced to death after attacking Draco Malfoy. As Black escapes on Buckbeak’s back, Harry and Hermione are able to free Sirius Black and send him away to live as a free man.

Overall, Harry Potter and the Prisoner of Azkaban is an exciting and heart-warming story about friendship, loyalty, and the true nature of good and evil.
