People of Praia da Vieira is one of Campos’ most original films. It illustrates the life of a fishing community in the central region of Portugal, an area very familiar to the director. The film shows aspects of the communities' migration from the sea to the Tagus River in search of calmer waters and their occupation of the riverbanks of the Ribatejo marshes, where they built small villages on stilts by the water's edge. The film uses footage from Campos’ early amateur fictional films from the late 1950s and 1960s, as well as other narrative devices, to tell the story of the place. The film diverts from a rigid ethnographical portrait and instead discovers a new way to approach the reality of these people living in post-revolutionary Portugal.
