Rural England, 1865. Katherine (Florence Pugh) is stifled by her loveless marriage to a bitter man twice her age, whose family are cold and unforgiving. When she embarks on a passionate affair with a young worker on her husband’s estate, a force is unleashed inside her, so powerful that she will stop at nothing to get what she wants. Lady Macbeth outclasses many of its peers in British period cinema, not because of its bold use of sex and violence, but because of its dramatic intelligence and its skill at filleting contemporary relevance from a classic literary source.
