In 2017, playwright Marco Canale staged a play called La velocidad de la luz (“The Speed of Light”) in the Villa 31 slum. There, a group of indigenous elderly ladies recovered their traditions in order to explore their bonds with modern culture, religion, politics and their own memories. Three years later, Canale replicated the idea in Japan and structured this film, together with Juan Fernández Gebauer and Ignacio Ragone, that revolves around that experience.
