General Macbeth (Michael Fassbender) is the cousin of King Duncan (David Thewlis) of Scotland. He fought against foreign enemies and quelled rebellions. On his way home one day, he met three witches who predicted that Macbeth would be promoted to a higher position, which made Macbeth eager to move. However, the one who will eventually inherit the throne is the son of General Banquo (Paddy Considine). Under the instigation of his wife (Marion Cotillard), Macbeth killed the king and ascended the throne. In order to keep the throne and the secret of regicide, Macbeth's hands were stained with blood. General Banquo, Lady Macduff (Elizabeth Debicki) and her children all died under Macbeth's butcher knife, and Macbeth was also going further and further on the road of madness.
