In this unhosted program, a film by the British Information Service traces the remains of graves, temples, houses, tools and other possessions of prehistoric civilizations in the United Kingdom. During the Old Stone Age, men hunted wild animals with crudely made tools and lived in caves. When the ice receded in the New Stone Age, the environment and geography of Great Britain was much changed, and men became farmers. Archaeologists interpret this history based on findings at such sites as the Windmill Hill settlement in the U. K., which has yielded the earliest examples of British pottery. Scenes from Skara Brae in the Orkney Islands show the extensive remains of this prehistoric village preserved by blowing sand dunes. And Belas Knap burial mound near Cheltenham reveals the stone chambers and tombs of that period. This two-part program concludes with the Bronze Age, when men learned to produce metals and create more uniform tools, such as a cast ax head.
