The time is just prior to World War II. Lovely Cluny Brown (Jennifer Jones) is the niece of a London plumber; when her uncle is indisposed, Cluny rolls up her sleeves and takes a plumbing job at a society home, where she meets a handsome Czech author (Charles Boyer) - a refugee who has fled the Nazis and now resides with a snobbish and stuck-up family. Hoping to advance herself socially, Cluny accepts a position as a maid in a fancy country home, where she once more meets the Czech author, who is a house guest; they promptly fall for each other, and Cluny follows his lead by turning her nose up at stiff-necked English propriety. is directed by the matchless Ernst Lubitsch.
