Daniel Kish lost his sight to retinal cancer before his first birthday, and by childhood had taught himself to navigate the world by clicking his tongue and reading the echoes that bounce back. Director Drea Cooper follows Kish as he bikes through traffic, hikes rocky trails, and describes the mental map his brain builds from sound alone, a technique close enough to sonar that people have nicknamed him "the real-life Batman." The film shows him training other blind people, especially children, to use the same clicking method instead of relying solely on a cane or guide dog, arguing that echolocation restores a kind of spatial independence most sighted people take for granted. Interviews with Kish are paired with footage of him in motion, letting the viewer hear the actual clicks and judge for themselves how much information they carry. It is a short, focused portrait of one man's adaptation and the method he now teaches to others.
