A man meets a woman who is the image of his late wife, which leads him to make many of the same mistakes over again in this drama. Shortly after the death of Katherine Mansfield, an author from New Zealand, her husband and editor John Middleton-Murray (John Gielgud) oversees the posthumous publication of several works that belatedly bring her fame and respect around the world. Thirty-three years after Katherine's passing, John travels to France (where Katherine died after contracting tuberculosis while traveling) to supervise the publication of a new collection of Katherine's journals and letters. While in Europe, John meets a young woman named Marie Taylor (Jane Birkin); she bears a striking resemblance to the late Katherine, and she also was born in New Zealand. As Jon and Marie get to know each other, Marie discovers just how much she has in common with Katherine -- and just how much was wrong with her relationship with John. Leave All Fair also features Simon Ward and Feodor Atkine.
