Prince Hamlet’s student friend, Horatio, goes to the battlements of Denmark’s Elsinore castle late at night to meet the guards. They tell him about a ghost they have seen that resembles the late king, Hamlet. It reappears and they decide to tell the prince. Hamlet’s uncle, Claudius, having become king, has now married Hamlet’s widowed mother, Gertrude.
In the court, after envoys are sent to Norway, the prince is dissuaded from returning to university. Hamlet still mourns his father’s death and hearing of the ghost from Horatio he determines to see it for himself. Laertes, son of the courtier, Polonius, departs for France, warning his sister, Ophelia, against thinking too much of Hamlet’s attentions.
