Trás-os-Montes (1976)

It's a docudrama with a poetic writing and non-linear narrative. Specifically, it's an "etnofiction": portraits the typical characters of Terra Fria, the North-east of Portugal, showing secular habits, in a majestic rural ambient. It's one of the works that represents the New Cinema (Novo Cinema) portuguese movement, and one of the first portuguese docudrama.
