In line with the increasing tensions between the the USA and USSR of the time, this play depicts 1970 with England as a bombed out radioactive waste land. However a valley somehow remains free of radioactivity and this is where a woman and her two children survive by farming. Their idyllic bliss is interrupted by a patrol from the US who tell them that they are collecting them to take them to live in the USA in a special contamination zone as they are going to nuke that valley to stop the USSR offering the same and claiming the land. Their suggestion is met with little enthusiasm by the family who want to stay where they are.
