King Hamlet of Denmark was poisoned by his brother Claudius. Not 2 months later his wife Gertrude marries Claudius unaware of his murderous ways. Hamlet and Gertrude have a son named Hamlet that comes home right before the wedding
The dead king comes back as a ghost at night to find Hamlet. He informs his son about the true nature of his murder and asks him to kill Claudius to get revenge for his death.
Hamlet makes his friends Marcellus and Horatio swear to not tell about the ghost.
Hamlet pretends to be crazy to figure out who he can trust. His girlfriend Ophelia tells her father Polonious about Hamlet's behavior and he believes that Hamlet is mad
Polonius tells the king and queen about Hamlet's madness and they set up a trap to prove if it is true.
Per the request of the king and queen Hamlet's childhood friends Rosencrantz and Guildenstern ask Hamlet about his feelings. Hamlet does not trust them since they did not show up when he needed them only when his parents requested them so he does not answer their questions
