On an ordinary morning in Fox Harbor, Wisconsin, Meg and Rex Van Dorn's lives are irrevocably changed when a drunk driver slams into Meg's car, killing the couple's six-year-old son, Evan. In a town in which everyone knows everybody else, it's no surprise that Meg and the driver, Cindy Ann Kreisler, were once the best of friends. Now, as Meg recovers from her own injuries, she and Rex find themselves unable to cope with their anger and despair, especially after Cindy Ann returns -- with a mere slap on the wrist -- to the life she lived before the accident: living in a beautiful house, enjoying her own three daughters, all of whom walked away from the accident unharmed.
