'It will have blood, they say: blood will have blood'

On a bleak, stormy night in Scotland, three witches prophesy: Macbeth will be a lord twice-over and Macbeth will be king; but Banquo's sons will also be kings.

When the witches' predictions start to come true, the ambitious Lady Macbeth vows to help her husband become King of Scotland and hold on to the throne - by any means necessary. But as the pursuit of power leads them down a dark and bloody path, the Macbeths soon begin to unravel.

Macbeth is Shakespeare's famously blood-soaked tale of greed and prophecy so powerful that superstitions about the curse of 'The Scottish Play' continue to this day.
