However, with the sudden death of her beloved Jack, and the return of her school bully - Bea - years later, Gertie's long buried trauma bubbles to the surface. All she can think about is one thing: Revenge. Inserting herself deep into Bea's life, nobody is safe - not her parents, not her children, not even the PTA members of her daughter's high school.
