A porter hears knocking at the gate of Macbeth’s castle. It’s Macduff and Lennox, who have come to rouse Duncan. Macbeth arrives and tells them the king is still sleeping. Macduff heads off to wake the king, and promptly returns, screaming bloody murder. He wakes up the whole castle, including Lady Macbeth, who pretends to be shocked and horrified at the news. As planned, everyone suspects Duncan’s servants. Macbeth has gone to see the murder scene for himself, and when he comes back, he tells everyone that he’s killed the servants in a rather swift act of vengeance. Macduff is about to challenge Macbeth on his rash actions when Lady Macbeth fakes a fainting spell and distracts the men. Meanwhile, a horrified Malcolm and Donalbain make plans to flee Scotland. After all, if Duncan is dead, they’re in grave danger.
