From the Oregon Trail in 1842 to hypertech SFBayCom in 2066, the narrative follows the encounters and exploits of 3 alienologists from a distant galaxy. They come to the "small blue sphere circling the minor yellow sun," enclone themselves into 3 murdered Chinese miners in the gold country, and begin exploring and studying.

Their lives and influence traverse through the American Civil War to the counterculture happenings of the 1960's and spread wide even to the Israeli-Palestinian conflict and a rebellion on Mars in 2066.
