David and Lisa lead a blessed life in rural Virginia; children, a summer-house by the river, warmth and laughter. Then their worst nightmare happens and their eldest son is killed. Utterly distraught, David enlists the help of an unconventional Rabbi and, by dangerously mixing age-old religious belief with cutting edge genetic science, a new son is cloned from the old one. A happy family life resumes but then disturbing things start to happen. The boy feels odd. The parents puzzlingly disconnected. Is nature fighting back? Is David's arrogance in playing God backfiring?
