Act I, Scene-V Detailed Summary of Hamlet: "Hamlet" by William Shakespeare

Here Hamlet is seen with the ghost which asks Hamlet to "revenge his foul and most unnatural murther" if he loves his father. Hamlet utters in emotional tone:

"Haste me to know't, that I, with wings as swift
As meditation or the thoughts of love,
May sweep to my revenge."

It further asks Hamlet :

"The serpent that did sting thy father's life
Now wears his crown".

So the mandate to kill his uncle is very clear while the ghost asks Hamlet to leave the matter of his mother to heavens. Hamlet vows never to remember anything but revenge of his father's murder. Enter Horatio and others but Hamlet does not tell the anything rather he asks them to vow that they shall never disclose to anyone of having seen the ghost. They promise. And Hamlet exits with the words:

"The time is out of joint. O cursed spite
That ever I was born to set it right!"
