Ninho de Rato delves into the idea of ​​anti-music and how it permeates the lives of those who come from the margins, the slums, the corners that almost no one looks at. The documentary explores these people's perspectives on the extreme music scene, how they live, feel, and give meaning to it all. It's about how anti-music becomes a space for respite, expression, and existence for those who carry the weight of the world and yet still create sound where no one expects it.
