A moment of random violence erupts in an ordinary Los Angeles diner. The survivors (Kate Beckinsale, Dakota Fanning, Guy Pearce, Forest Whitaker) find that the meanings of their lives have changed. No matter how much their families and friends (Jennifer Hudson, Jackie Earle Haley, Jeanne Tripplehorn, Embeth Davidtz) attempt to understand, these individuals must follow their own paths to recovery seeking to regain trust in a world that now seems chaotic.
