Wearing her original prom dress from 1960, Peggy Sue Bodell (Kathleen Turner) sets off for her 25-year high school reunion in 1985 with her daughter, Beth, as company. Peggy Sue has just separated from her high school sweetheart, now husband, Charlie (Nicolas Cage) due to his infidelity. She is wary of attending the Class reunion because of everyone questioning her about Charlie's absence - they were married right after graduation, when Peggy Sue became pregnant.
