In Shakespeare's verbally dazzling and eternally enigmatic exploration of conscience, madness and the nature of humanity, a young prince meets his father's ghost in the middle of the night, who accuses his own brother - now married to his widow - of murdering him. The prince devises a scheme to test the truth of the ghost's accusation, feigning wild insanity while plotting revenge. But his actions soon begin to wreak havoc on innocent and guilty alike.
