Amanda Vaughn (née Stopper), a single mother who moves back to her home town after her husband, Bill Vaughn, died in a car crash in California, where Amanda had originally relocated in order to escape her hometown Highland Park, Texas. She currently lives with her mother, Gigi Stopper.
Back in Texas, she's greeted by girls that she used to go to high school with. Amanda used to be the "GCB" in high school, creating a hierarchy system which targeted many of the girls she returns to see. Amanda has changed however, but these girls (Carlene, Cricket, Sharon) have not and they now want their revenge on her.
