Dublin 1907, a city of whispered rumours. 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. Witty and watchful, she has dozens of admirers. But in the backstage of her life, there is a secret.
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.
