On a bleak Scottish moorland, Macbeth and Banquo, two of King Duncan's generals, discover three strange witches. The witches prophesy that Macbeth will be promoted twice: to Thane of Cawdor and King of Scotland. The witches also prophesy that Banquo's descendants will be kings. The generals want to hear more, but the "weird sisters" disappear.
Soon afterwards, King Duncan names Macbeth Thane of Cawdor as a reward for his success in the recent battles. The promotion seems to support the prophecy. The King then proposes to make a brief visit that night to Macbeth's castle at Inverness. Macbeth must decide if he will help the prophesy along to make Scotland a better kingdom with him at the reigns. Will Macbeth become king? Will he be able to handle the blood on his hands required to gain the throne? Will it forever change him and all his relationships?
