Laney (Sarah Silverman) is an attractive, intelligent suburban wife and devoted mother of two children. She has the perfect husband (Josh Charles) who plays basketball with the kids in the driveway, a pristine house, and a shiny SUV for carting the children to their next activity. However, just beneath the façade lie depression and disillusionment that send her careening into a secret world of reckless compulsion. Only very real danger will force her to face the painful root of her destructiveness and its crumbling effect on those she loves.
