In the stifling suburban world inhabited by Joanna Kendall, very little happens to change the meticulously planned existence. That is until she accidentally hits an eight-year-old girl who has dashed in front of her car. Her nightmare only worsens when, after calling for help, she chooses to drive on rather than take responsibility for what's happened. While nvestigators continuing their search for the cowardly hit-and-run driver, she begins taking stock in herself by questioning the number of decisions and sacrifices she's made in her role as the ideal wife. And as the pressure of keeping up this innocent homemaker charade intensifies, it is only a matter of time until this guilt-wracked woman finally breaks under the weight of her own conscience.
