The play is about a great soldier Macbeth whose fate is tempted by 3 witches. He decides with the help of his wife to kill the king in order to take over Scotland. Once he kills, his paranoia only gets worse and he continues to kill in order to stay in power. His wife, as time goes on, only grows crazier because of her guilt. She was pretty insistent in the beginning because of her own greed, but after taking part in the murder, she is no longer able to sleep and eventually takes her own life. Macbeth then becomes so over confident that he doesn't realize that Macduff is the one who will kill him and end his reign. After a battle, Macduff kills Macbeth and the chaos subsides while Malcolm rightfully becomes king of Scotland.
