In a suburban neighborhood in Waco, Texas, live the O’Briens. The young couple is enthralled by their new baby Jack and, later, his two brothers R.L. and Stevie. When Jack reaches adolescence, he is faced with the conflict of accepting the way of grace or nature, as embodied by his parents. Mrs. O’Brien, the embodiment of grace, presents the world to her children as a place of wonder. Mr. O’Brien, the embodiment of nature, easily loses his temper as he struggles to reconcile his love for his sons, wanting to prepare them for a world he sees as corrupt and exploitative.
