Four humans find themselves in a small village of Betaham without knowledge of where they come from or who they are. It is a pleasant little town but disturbing memories of a brutal war and a different life flash spasmodically into their minds.

Their dreams seem so real but are quite unrelated to their present lives ... that is until they meet a strange farmer and a violent sandstorm arrives at Betaham. They find the farmer isn't even human. Furthermore, they may not even be human themselves.

A bombed out city is on the other side of the hills and can be reached though a railway tunnel. The trouble is that the city was destroyed a millennium before and is an archaelogical site visited by the farmer's race who arrived from another planet.

Only then do the four learn the truth about themselves...
