Dublin, 1907: a city of whispered rumors. An actress still in her teens begins an affair with a damaged older man, the leading playwright at the theatre where she works. Rebellious, irreverent, beautiful, flirtatious, Molly Allgood is a girl of the inner city tenements, dreaming of stardom in America. Her lover, John Synge, is a troubled, reticent genius, the son of a once prosperous landowning family, a poet of fiery language and tempestuous passions. Yet his life is hampered by Edwardian conventions and by the austere and God-fearing mother with whom he lives. The affair, sternly opposed by friends and family, is turbulent, sometimes cruel, and often tender. What is to become of each of them?
