A three-act drama traces the unraveling of a fashionable London household as a glamorous, self-indulgent mother and her emotionally volatile son confront secrets, vanity, and substance dependence. Social gatherings, romantic entanglements, and theatrical circles form the backdrop for brittle relationships and generational friction. Sharp domestic scenes and wry conversation expose characters’ self-deceptions, hypocrisy, and the corrosive effects of fame and desire, leading to painful reckonings that force private failings into public view.
