The Partridge Family does a show at a large amusement park in Cincinnati, after which they spend the day as visitors in the park, enjoying all the rides. That is, everyone but Keith who is afraid of heights and gets sick on every ride, including the merry-go-round. When they are informed that a public relations man is coming to show them around, Keith bows out, feeling sick. When the PR man turns out to be very attractive, 30-year old Audrey Parsons, Keith makes a miraculous recovery. Keith then falls madly in love with Audrey, trying his best to impress her, but succeeding only in making a fool of himself. When Shirley tries to tell Keith that he is too young for Audrey, he won't listen. Danny decides to help Keith by making him realize that he hasn't got a chance, which he will do by making Audrey fall in love with him. When Keith tries to get a date with Audrey he finds she already has a date -- with Danny! The three of them spend the day going on rides. The day ends with Keith getting sick and Danny falling in love with Miss Parsons. Keith thinks Danny is behaving foolishly because he is too young and then realizes that he had behaved the same way. When Audrey turns down Danny's request for a date, he is finished with women. The show ends with Reuben trying to get a date with Audrey.
