On marrying the boss's daughter, Richard takes his father-in-law's advice to hire a live-in domestic. He soon finds good help is hard to come by. Run-ins follow with dipsomaniacs, bank robbers, a Welsh lass who takes one look at London and runs, and an Italian charmer who turns the place into a bawdy house. Then when Ingrid arrives from Sweden things actually start to get complicated.
Unfortunately the movie Upstairs and Downstairs is not yet available on Disney Plus.
