It’s Harry’s (Daniel Radcliffe) fifth year at Hogwarts and the magical community are in denial about Harry’s last encounter with the dark lord Voldemort (Ralph Fiennes). It seems they are all buying into the propaganda of the Minister of Magic; Cornelius Fudge (Robert Hardy).

Believing that the rumours are false and the work of Dumbledore (Michael Gambon), Fudge decides to station one of the ministry’s best at the school. Dumbledore is forced into hiding and Delores Umbridge (Imelda Staunton) takes the role of headmistress, but her way of teaching is not the way the students are used to, and the students soon realise that they will need something much more effective than Umbridge’s Ministry-approved course of Defence Magic if they’re going to survive the tasks that lay ahead.

Hermione (Emma Watson), Ron (Rupert Grint) and Harry decide to take matters into their own hands and teach underground lessons in Defence against the Dark Arts to a portion of the student body, they begin to advance and name themselves ‘Dumbledore’s Army’, they will be ready for the tasks ahead!
