In Harry Potter and the Order of the Phoenix, Harry is plagued by nightmares about the return of Lord Voldemort. However, when he tries to warn the Ministry of Magic and his fellow students, no one believes him. Meanwhile, Hogwarts is under the control of Dolores Umbridge, a new professor who is determined to suppress any talk of Voldemort’s return and exert complete control over the school.
Frustrated with the lack of action being taken against Voldemort and Umbridge’s oppressive regime, Harry decides to form Dumbledore’s Army, a group of students who secretly train in defensive spells and magic. The group becomes increasingly skilled in their abilities, but they are eventually discovered by Umbridge and face severe punishment.
As tensions rise between Harry and Umbridge, he begins to have disturbing visions that lead him to believe that Voldemort is after an important prophecy that he and Voldemort’s henchmen, the Death Eaters, will stop at nothing to retrieve. Harry and his friends set out to find and protect the prophecy before it falls into the wrong hands, leading to a final showdown between Harry and Voldemort.
Throughout the film, Harry struggles with feelings of isolation and frustration as he grapples with the burden of being the sole person who knows the truth about Voldemort’s return. He finds support and comfort in his friends Hermione and Ron, as well as the wise guidance of Dumbledore and other members of the Order of the Phoenix, a secret society dedicated to fighting against Voldemort and his followers.
