At an exclusive restaurant called Above The Top, which is located at the roof of a luxurious hotel in downtown Los Angeles, California, a group of five women work there as waitresses: Lois Adams, a married mother of two children(a boy and a girl), Jan Hoffmeyer, a divorced mother of one child(a daughter named Ellen) who goes to college during the day, Dorothy "Dot" Higgins, an aspiring actress who waitresses at the restaurant to supplement her income while pursuing her acting career, Vicky Allen, a farm girl from Idaho who is new to Los Angeles and is learning the ways of a major city, and finally Cassie Cranston, the attractive, sassy member of the quintet who is the wisecracker of the bunch.  In this, the very first episode of the series, Vicky is dating a pilot who invites her to spend the weekend at Palm Springs, but this causes a problem for her because she is a virgin. 

The girls of Above The Top convince Cassie to let Vicky move in with her while Vicky's situation with her new apartment gets solved, but when Vicky finds out that the current tenants of her new apartment have yet to move out, Vicky's stay at Cassie's place stretches to a week, causing friction between the two coworkers over Vicky's tidiness and cooking.
