Adapted from a J.B. Priestley play with many of the original actors. The tale of various people who have come to live in an "ideal" city and their hopes and reasons for doing so.

Nine Britons are transported to a mysterious city where, according to their class and disposition, they find themselves either in an earthly paradise of peace and equality or a hell starved of ambition and riches. From J B Priestley, this fantastical allegory is a striking expression of post-war utopian impulses and among Ealing's most unusual features.
