The rebellion begins! Lord Voldemort has returned, but the Ministry of magic is doing everything it can to keep the wizarding world from knowing the truth - including appointing Ministry official Delores Umbridge as the new defense against the dark arts professor at Hogwarts. When Umbridge refuses to teach practical defensive magic, Ron and Hermoine convince Harry to secretly train a select group of students for the wizarding war that lies ahead. A terrifying shutdown between good and evil awaits in the enthralling film version of the fifth novel in J.K. Rowling's Harry Potter series. Prepare for battle!
