"La cosa vuestra" is a journey towards the most hidden and surrealist side of sanfermines; it is an empowering reflection compared with the violence exerted against women. Fun and stark reality working on iconographic cannibalism. What have the San Fermín Festivals become and where are they headed? This guerrilla video shows drifting heterodoxes and hibridations, savage visions and palpitations of the Navarra idiosincracy, from the “video machine” to the “laughter technique”. It is a critical montage of the aesthetic, ritual and cultural universe of Pamplona. "La cosa vuestra" tries to reinvent imaginaries through activation hacking, video-collage, grotesqueness, futuristic dystopia and the transgression of film, popular culture and the media.
