Robin and Hazel, a long-married couple, have retired to a farm by the  sea. Their life is self-sufficient and apparently tranquil, until the arrival of an unwelcome figure from the past forces them to contemplate the  world beyond their front door. This disturbing, compelling drama, set in the wake of a disaster at the nearby nuclear power plant, considers the personal responsibility of past and present generations for actions that will have profound consequences for our children.
