In Richmond, England in 1923, Virginia Woolf is setting out to write the first words of her new book. In Los Angeles in 1951, a housewife, Laura Brown, is contemplating suicide. And in present-day New York, a hostess, Clarissa Vaughan, is planning a party for her friends. In extraordinary and ingenious ways, the film shows how a single day - and the novel Mrs Dalloway - inextricably link the lives of three very different women.
