My home is my castle. In order for this saying to be true servants, who live downstairs, and the gentlemen upstairs have to create a harmonious ensemble, where everyone knows his role and is conscious of his actions. The film is a touching story about the relationship between “upstairs” and “downstairs”, about understanding, tolerance, tact, loyalty and gratitude of all manner of men. Upstairs is a young diplomat Sir Hallam Holland with his family. Downstairs is a skilled housekeeper Rose Buck and servants. The action takes place in 1936. Britain is on the eve of war.
