Justine Last (Jennifer Aniston) works a mundane job at the Retail Rodeo.  She goes home each night to her stoned couch potato husband and follows the same routines, deadened by the unending repetitiveness of her days.  Justine feels confined by her obligations, gathering meaning from nothing day-to-day.  This makes for an explosive situation in the film The Good Girl, especially when her comfortably numb existence gets a glimpse of her untouched emotions.
