The film uses the city's rigid geometry to highlight the isolation of its characters. The "18% humidity" of the title underscores a physical and emotional dryness. In this environment, human connections are transactional, and the grand vistas of the capital become a stage for shadow plays and clandestine meetings. Political Commentary and the "Mensalão"

Nelson Pereira dos Santos, a foundational figure of Brazil’s Cinema Novo , utilized his 2006 film Brasília 18% to craft a surreal, somber, and deeply critical portrait of the Brazilian capital.
