In "Harry Potter and the Half-Blood Prince", Voldemort is tightening his grip on both the Muggle and wizarding worlds and Hogwarts is no longer the safe haven it once was.
Harry suspects that dangers may even lie within the castle, but Dumbledore is more intent upon preparing him for the final battle that he knows is fast approaching.
Meanwhile, the students are under attack from a very different adversary as teenage hormones rage across the ramparts.
He is determined to make his mark, albeit a dark one. Love is in the air, but tragedy lies ahead and Hogwarts may never be the same again.
See Harry and friends in action before the movie hits the cinema.
