We are in Barcelona in the late 19th century. The old city walls have just been torn down, finally freeing the city's growth outward towards the old villages that surround it. Based on the plans by Cerdà, the construction of Barcelona's famous Eixample (Catalan for "expansion") has begun. It is a period of great prosperity when the burgeoning upper middle class families found their fortunes and used their wealth to demonstrate their power by constructing unique buildings and supporting initiatives for the city's inhabitants. However, not everything is so pleasant in the city. Its prosperity is drawing more and more people to work in the big city, and revolutionary movements are taking hold among the city's unemployed workers.
