On a warm spring day in 1924, housemaid and foundling Jane Fairchild finds herself alone on Mothers Day. Her employers, Mr and Mrs Niven, are out and she has the rare chance to spend an afternoon of abandon with her secret lover, Paul, the boy from the manor house nearby. Paul is Janes long-term love despite the fact that he's engaged to be married to another woman, a childhood friend and daughter of his parent's friends. But events that neither can foresee will change the course of Jane's life forever.
