Hamlet races into the woods, following the ghost of King Hamlet. His father explains he has been poisoned and he wants Hamlet to revenge his death. Hamlet agrees.
Murder most foul, as in the best it is, But this most foul, strange, and unnatural.
Hamlet goes to confront his mother, in whose bedchamber Polonius has hidden behind a tapestry. Hearing a noise from behind the tapestry, Hamlet believes the king is hiding there. He draws his sword and stabs through the fabric, killing Polonius.
Oh, I am slain.
Oh, what a rash and bloody deed is this!
Laertes is stabbed by his own poisoned sword and falls. Gertrude drinks from the poisoned goblet and slowly dies as Hamlet is sliced with the poisoned blade as well. But before he he dies, he stabs Claudius and makes him drink the rest of the poison, finally getting his revenge.
