Harry is attacked near home by dementors. He protects himself by magic but
he's then asked to defend himself in front of a court of wizards. The point is
that the Minister of Magic refused to believe him when he claimed that
Voldemort is back, and tries to silence him. He also meets the Order of the
Phoenix, an organisation founded by Dumbledore to fight Voldemort over a
decade ago, which all his adult friends are members of. Back at Hogwarts,
Harry and his friends face their new teacher of Defense Against the Dark Arts,
Dolores Umbridge, a member of the minister who reforms the teaching in order
to prevent the students to learn any useful fighting magic and become
“Dumbledore's Army” that would, in the Minister's paranoia, take over the
Ministry. Therefore, Harry, Ron and Hermione decide to create a secret
association for teaching proper defensive magic to the students, without
Umbridge knowing. Harry also has weird dreams, induced by Voldemort, where he
see Ron's father being attacked inside the Ministry while patrolling by night.
At Hogwarts, the situation has become worse than ever, with Umbridge getting
appointed Inquisitor, and then Headmaster. When Harry sees his godfather being
killed by Voldermort in the Ministry, he decides to go there, along with his
best friends. Umbridge tries to stop them, but they manage to get rid of her
and fly to London, to the Ministry. There they fight Deatheaters, who are
trying to get their hands on a prophecy on ehalf of their master. Harry
manages to listen to it before it gets destroyed. It was about him and
Voldemort not being able to be alive both at the same time, one having to kill
the other. During the fight, Sirius gets killed. Then VOldemort himself comes
and attacks Harry, who is saved just in time by Dumbledore. The Minister
arrives on the ground just before Voldemort escapes; he now has to acknowledge
his return.
