When the Wind Blows

Middle-aged Jim Bloggs becomes troubled at the mounting possibility of nuclear war. His wife Hilda is too busy with housework to be at all concerned. Jim returns home with some civil defence pamphlets and attempts to build a fallout shelter in his living room.
And then the nuclear strike comes. They make it to the shelter in time but when they emerge they too have to cope with the drastically changed world. At first they discover that this means wondering when milk and newspaper deliveries will resume and that there is no power to boil a cup of tea, but soon come to realise that the devastation is much wider than that.
