Prompted by the prophecies of three mysterious witches and goaded by his ambitious wife, the Scottish thane Macbeth murders Duncan, King of Scotland, in order to succeed him on the throne. This foul deed soon entangles the conscience-stricken nobleman in a web of treachery, deceit and more murders, which ultimately spells his doom. "Macbeth" paints a striking dramatic portrait of a man of honor and integrity destroyed by a fatal character flaw and the tortures of a guilty imagination.

This radical reimagining of one of Shakespeare’s most deeply psychological plays is set in a psychiatric unit in which narrator and acclaimed film, stage and television actor Alan Cumming is the lone patient. Channeling the story of Macbeth, he is inhabited in turn by each of the characters of the drama, including some of Shakespeare’s most complex and troubled creations.
