After suffering a savage assault in a bathroom as a girl, Gertie meets the man of her dreams. Her trauma soon vanishes as they begin to build a life together. 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. Starting a sordid romance with Bea in a bid to destroy her life from the inside out, Gertie soon learns revenge is messier than she thought. But a girl's gotta do what a girl's gotta do.
