Downstairs, Upstairs is centered around a house maid named "Olive." Olive's job is with the uproariously sex happy Bunn family. The family includes Sheila Bunn, Mr. Bunn and his wife, Muriel Bunn. As the picture builds to a hot climax, Manners, the butler, joins Olive and Sheila in a menage-a-trois. The incredible scenes that follow are the most erotic and sexual ever shown on the screen. *Adult-film debut of Sherrisse.
