Plot Storyboard

Overview of Macbeth

Macbeth is a five-act tragedy, written by William Shakespeare in 1606. Set in medieval Scotland, it mainly takes place in and around Macbeth’s castle, Dunsinane.

Its protagonist, Macbeth, is at first presented as a noble warrior and thane who is loyal to his king. However, a combination of his ambition, the prophecies of three malevolent witches and the encouragement of his equally ambitious wife, Lady Macbeth, sees him assassinate his king, Duncan, and ascend the throne himself. 

While King of Scotland, Macbeth becomes increasingly paranoid that his act of regicide will be discovered, and that he himself will be murdered, and so Macbeth attempts to murder any person he sees as a threat (first his friend and comrade Banquo; later a thane called Macduff). 

However, overwhelming guilt consumes both Macbeth and Lady Macbeth: Macbeth sees hallucinations – including of his murdered friend Banquo – and seeks the dangerous advice of the witches for a second time, while Lady Macbeth loses her mind completely and commits suicide. 

The play concludes with Macduff (who managed to escape Macbeth’s assassination attempt) killing Macbeth in a duel, thus avenging both his family, whom Macbeth cruelly murdered, and his former king. Order is thus restored in the Kingdom of Scotland, with Duncan’s son, and rightful heir to the throne, Malcolm, becoming king.
