In the glossy adaptation of JK Rowling's sixth novel of her seven-book saga, the Dark Wizard Voldemort is tightening his grip on both the Muggle and wizarding worlds.
The Hogwarts School of Witchcraft and Wizardry is no longer the safe haven it once was - and Harry Potter begins to suspect that dangers lie within the castle.
Meanwhile, headmaster Dumbledore is intent upon preparing the teenage wizard for the final battle that he knows is fast approaching.
Danger may be looming, but that doesn't stop Harry and his classmates becoming embroiled in some good old-fashioned adolescent angst.
