The radio "The Time Machine," which transports people between the past, present, and future, presents a special program featuring a flower seller, an engineer-architect, a photographer, and a group of musicians, all from the 1930s and transported directly to the 2020s. Lost within a building they know as the Banco do Brasil agency in São Paulo, they interact with the audience while presenting the history of the city's growth and transformation into a major metropolis. They explore the establishment of the Banco do Brasil agency in its first building in the city, as well as the architectural details of the building, ultimately discovering that, in the future, the building serves a new function: safeguarding culture and art as the Centro Cultural Banco do Brasil.
