Summary: Researchers at a megacorporation discover a technique for making a present-day duplicate of any past thing or person that can be located exactly in time and space. The owner and chief executive of the corporation decides that the ideal way to announce this discovery to the public is to hold a “family reunion” in which ten of his illustrious ancestors are recovered from their times and brought forth to celebrate the corporation's power and ingenuity.
The results are predictably comic, since the character traits and patterns of behavior that made the ancestors so illustrious are much less esteemed in mainstream contemporary Western society.
Playing for laughs, Brunner also reduces most of the ancestors to stereotypes, in ways that are likewise much less esteemed in mainstream contemporary Western society than they were in 1969.
