Act Four occurs around a year after the previous acts. Anna has died, and Ivanov and Sasha are preparing to marry. As the wedding is about to begin, Lvov appears, planning to unveil Ivanov's 'evil' intentions – believing Ivanov is simply marrying Sasha for the dowry. He makes the accusation publicly and even though other characters have previously expressed doubts they all leap to Ivanov's defence and challenge Lvov to duels. Ivanov finds the whole situation amusing, returning to his old self, and takes out his gun. Sasha realises what he is about to do, but is unable to stop him: Ivanov runs away from the crowd and shoots himself, abruptly ending the play.
