This article analyzes the ethnographic documentary Escucha la voz de los que no pueden hablar (Listen to the Voice of Those Who Cannot Speak, 2004; 40 min 42 s), shot on Mini DV in the low-income neighborhoods of Valdivia, Chile, by the author, then an anthropology student and resident of the area. Drawing on a review of the complete documentary, the transcription of its testimonies and their organization into thematic clusters, it examines the interpretations that its protagonists —homeless people, most of whom self-identify as Mapuche— develop about progress, racism, memory and exclusion. It discusses the notion of the camera-bond, its scope and limits in relation to shared anthropology, and proposes a reading of alcohol consumption that distinguishes sociability, suffering and harm.
