In Denmark, the former king has died and two soldiers inform his son, Prince Hamlet, that they saw his ghost. It is revealed that his father was poisoned by his uncle, who has usurped the throne and the queen.
How dangerous is it that this man goes loose
Hamlet uses tactics to prove Claudius killed his father. He requests that a theater troupe acts out a play that depicts a king being poisoned in the ear. Claudius' reaction will prove his guilt or innocence.
Claudius leaves the play and goes to pray for forgiveness for killing Hamlet's father. Hamlet overhears this and wants to kill him. However, Hamlet thinks if he kills Claudius while he is praying, Claudius will go to heaven and he would go to hell.
Tell my story, Horatio
