Macbeth is a tragedy about betrayal and excessive ambition. It is freely based on the story of the life of a historical character, King Macbeth of Scotland.
Lady Macbeth's plan is to get the guards drunk at night so that her husband could infiltrate the king's room to kill him. Banquo replies that he would do things to win Macbeth's favor as long as it did not affect his honor or go against his morals.
