Just before dawn the play's characters - who represent every stratum of society - come to the wall overlooking a strange city whose gate is shut against them. At daybreak they are admitted and towards the end of the day some have found it to be the ideal earth has never achieved. So that everyone may know of this attainable perfection two of them make the sacrifice of leaving the city to return to their sinful world. Contained in the volume Priestley Plays II.
