However, when Blair sets Sue Ann up on a blind date which will involve going swimming, Sue Ann goes on a starvation diet leading to a collapse. Meanwhile, Mrs. Garrett also jumps on the dieting wagon, trying to fit in a size 12 dress.

Mrs. Garrett begins teaching a sex-education class at Eastland and her tactics are against the more prudish suggestions of Mr. Bradley. Meanwhile, Blair takes the ideas from class and expirements with her latest boyfriend, Steve.

Mr. Bradley's need to have Eastland win prompts him to manipulate Sue Ann into competing in a running competition. Sue Ann had previously ran but this year decided not to, however, Mr. Bradley uses Cindy's better racing times to goad Sue Ann into competing.
