In the sixties, just before starting his career as a feature film director and his parallel career of the Anticine, Javier Aguirre had a brief career as a documentary filmmaker, which served him to test and rehearse many procedures that he would put into practice in the avant-garde aspect of his work. The trail belongs to that period, a few years full of mystery, but whose works are emerging demonstrating the portentous gaze of Aguirre. The trace has hardly been seen in the last sixty years, and it is an opportunity to recover this vision between anthropology and the vanguard of one of the hallmarks of this city. The film has been restored by the ECAM Archive in collaboration with Filmoteca Española.
