"Good things of day begin to droop and drowse, While's night's black agents to their preys do rouse." The brave warrior Macbeth allows himself to be persuaded by Lady Macbeth, his wife, to slay good King Duncan and seize the throne of Scotland for himself. Macbeth achieves his ambition, but one murder proves not to be enough. Sinister supernatural forces are at work in this fast-paced tragedy of guilt and retribution, in which the power of human beings to control their own destiny is called into question.
