Absorbed in her own failings, 43-year-old Clara Purdy crashes her life into a sharp left turn, taking the young family in the other car along with her. When bruises on the mother, Lorraine, prove to be late-stage cancer, Clara moves the three children and their terrible grandmother into her own house while Lorraine undergoes treatment at the local hospital. We know what is good, but we don't do it. In "Good to a Fault", Clara decides to give it a try, and then has to cope with the consequences: exhaustion, fury, hilarity, and unexpected love. But she questions her own motives. Is she acting out of true goodness, or out of guilt? Arid most shamefully, has she taken over simply because she wants a family of her own?
