Amanda Vaughn, once the ultimate high school “mean girl,” is forced to return home in disgrace after her marriage ends in scandal. Amanda is nothing like the girl she was 20 years ago, but as her old classmates reacquaint themselves with the new Amanda, will her home town welcome her with open arms or seek revenge? No one in this town is a saint, but that doesn’t mean they can’t have a heart. As Amanda and her teenage kids try to adjust to their new lives, the ladies from her past alternate between sympathy and scheming.
When former mean girl Amanda Vaughn moves back to Dallas 18 years after high school, former unpopular teen-turned-diva-of-Dallas Carlene Cockburn gets a major dose of PTSD. To top it off, Amanda’s living across the street from the Cockburns with her feisty mother Gigi Stopper! Amanda has changed for the morally better but Carlene and her other victims – the GCBs – have their doubts. The GCBs now rule the school that is Dallas society and are about to settle the score with Amanda Vaughn.
