I Smile Back explores the life of Laney (Sarah Silverman), an attractive, intelligent suburban wife and devoted mother of two adorable children. She has the perfect husband (Josh Charles), a pristine house, and a shiny SUV for carting the children to their next activity. However, just beneath the facade 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.
