On a road trip through the dusty heart of the USA a researcher intends to make physical contact with a phantasy, traversinga mythical non-place between East and West, masculine and feminine, material and projection, past and future. Meeting fossil traders, sculptors and scientists on both sides of the American Frontier, they are trying to reconstruct the plot of natural history, the plot of progress. The story ends in the middle, in Rapid City, South Dakota, at the foot of an imported Berlin wall fragment. But the journey continues.
