Behind the eucalyptus trees was born from a collaborative project carried out with the residents of Llanos del Sotillo, a colonisation village built in southern Spain between 1956 and 1962. It was planned by José Antonio Corrales, a young, internationally renowned architect, using a radical design based on an abstract, four-by-four metre graticule. Among its transgressive peculiarities, highlights include streets covered by the homes themselves, their layout in a comb formation, and the absence of characteristic façades, except for a monumental bell tower topped with a cross.

Alongside the film, a collective historiography project was undertaken, with copies of the original plans for the village, photographs contributed by the residents and drawings by the local children.
