What happens in the exposition of a play

the central problem and main character introduced

In the exposition of a play, the setting and characters are introduced, and the central problem or conflict that will drive the story forward is established. The main character's background, motivations, and goals are also typically established during this phase of the play. The exposition sets the stage for the events that will unfold in the rest of the play and gives the audience a sense of the world in which the story takes place.
