Armed with an out-of-date book on housekeeping, Anna determines to become a housemaid, and she finds work at the Earl of Westerholme's crumbling but magnificent mansion. The staff and the family are sure there is something not quite right about their new maid - but she soon wins them over with her warmth and dedication.
Then the young Earl returns home from the war - and Anna falls hopelessly in love. But they can never be together - Rupert is engaged to the snobbish and awful Muriel. And anyway, Anna is only a servant. Or so everybody thinks.
