The film serves as a poignant counter-response to the significant investments made in recent years in the construction of large hydroelectric plants in Brazil, which have been positioned as solutions for the country's economic growth. In a short but impactful format, the film highlights the socio-environmental issues that have arisen as a direct consequence of these ambitious projects.

Specifically, the film investigates the experiences and challenges associated with three notable hydroelectric plants: Sobradinho in Bahia (constructed between 1971-1978), Belo Monte in Pará (constructed between 2011-2019), and the planned Panambi plant in Rio Grande do Sul. Through the voices of people directly affected by these projects, the film provides a platform for individuals and communities to express their perspectives, grievances, and concerns.

One of the most compelling aspects of the film is its emphasis on the intangible costs incurred by these gigantic undertakings. Beyond the physical and environmental impact, the film highlights the human and cultural cost that accompanies these projects. It underscores the often-overlooked emotional and social consequences that can result from large-scale industrial developments, shedding light on the stories of people and communities who find themselves confronted with profound changes to their way of life and environment.
