A contemporary comic drama set on the seismically active, tsunami-eroded, albeit beautiful, rural coast of Angelsea, England in the environs of a compromised nuclear power plant. Does that sound a bit like our home? While the world outside is dealing with the aftermath of the disaster at the plant, married couple Hazel and Robin, nuclear physicists who worked at the now-failed plant, are visited by a former colleague who upsets the balance of their already precarious existence with both humourous and far-reaching effects.
