The plot revolves around a pair of buildings constructed from the same architectural plan. One stands on a wide, wealthy avenue and the other on the forgotten alley of a fringe neighbourhood.Architecturally, the buildings and their plans are identical, but their uses and the people and businesses that inhabit them could not differ more. Combining the striking projections of Katchor's comics with powerful virtuoso performances, the production inventories the contents of the buildings, explores the parallel yet opposite lives of their inhabitants, and uncovers the strange and hilarious places in which the two worlds overlap, finally bringing together the odd lives of each building over a single piece of cherry cheesecake.
