Summer of 1963. Carson is getting married to her boyfriend so her friends Melaina, Pudge and Luanne take her to Myrtle Beach for one last irresponsible weekend. Before adulthood takes hold, four teenage girls spirit away to Myrtle Beach, S.C., for a final vacation together. And all of them have their issues: Carson (Phoebe Cates) is marrying a boy who might not be right for her, Melaina (Bridget Fonda) obsesses over her Hollywood dreams, Pudge (Annabeth Gish) has self-esteem problems and Luanne (Page Hannah) has a hard time letting loose. But as the trip continues, the four grow closer together and help each other start to figure things out.
