Entering Normal : Rose Nelson is a middle-aged woman with a broken past, a sorrow from which she cannot recover. Secretly guilty about her role in her teenaged son's death five years ago, she has sealed herself off from life, enveloped by a grief that has slowly eaten away at her relationship with her husband. Against her will, Rose is drawn into the world she has avoided when Opal Gates and her five-year-old son, Zack, move in next door. Determined to start an independent life for herself, twenty-year-old Opal has left her family and the father of her son in North Carolina. But when she quickly begins an affair with Tyrone Miller, a part-time mechanic and local musician, Opal unwittingly breaks the tacit rules of both her family and her new hometown. Initially, Rose cannot bear the sight of Opal and her son. But later when Zack is injured, she instinctively lies to protect Opal from a single mistake that changes the lives of everyone involved. Faced with a custody suit brought by Zack's father and her own parents, Opal faces a trial in which each choice she has made will be used as ammunition in the battle to take Zack away from her.
