She is somewhat concerned at having been hired sight unseen, but on her arrival at Brymton Hall she finds both her employer and the other servants in the house to be quite amenable. Mr. Brympton on the other hand is rude and nasty to his wife, but fortunately is frequently away and Mrs Brymton has formed a close friendship with a neighbor, Mr. Ranford. Shortly afterwards things get strange. (imdb)
