"The plot has Janis, who has been hurt more than once, convincing Cady to go deep undercover as a "Plastic," the derogatory name for Regina's group of little bitches. Cady is supposed to find dirt on Regina and use it against her. As an undercover narc will admit, entering a scene can change you. Soon Cady becomes less and less like her old friends and more and more like her evil new ones. In some of the movie's more original moments, the students start acting out the same animal behaviors that Cady once observed in the wild out on the savanna. The fountain in the local mall, for example, is transformed into an ***animal watering hole***." http://www.allmoviephoto.com/photo/2004_Mean_Girls_photo.htm...
