Macbeth, a general who serves the King Duncan of Scotland, is told by three witches they predict he will become King of Scotland.
King Duncan rewards Macbeth's service, and Lady Macbeth convinces him to murder the king while they stay as guests in his castle. Macbeth does this and becomes king. To secure his high position, he has Banquo, another general in service of the king, murdered.
Macbeth is told by the witches to beware of Macduff, a noble who has fled to England. However, they tell him, he cannot be harmed by any man born of woman. Macbeth orders the murder of Macduff's wife and children.
In England, Macduff and Malcolm raise an army to defeat Macbeth. Macbeth believes he has nothing to fear, as no man born from a woman can harm him.
Macbeth finds out his wife has killed herself. Macbeth faces Macduff, but finds out he was born by Caesarian section, and loses the battle. After Macbeth dies, Malcolm takes the throne.
