The Enterprise responds to a call for help from Galaxy Class sister ship U.S.S. Yamato. But when the Yamato suddenly explodes the Enterprise crew must determine if the ship's destruction is caused by Romulans or by the relics of a long lost civilization.

Data gets to do some physical comedy, Romulans are terrible bluffers, and the city of Toronto is featured as an alien space building. Ruthie and Matthew talk about the coolness of space archeology but also the destructive effects of colonial archeology and anthropology in our own history.
