Lightning is a combination of thunder and intense electromagnetic radiation, whose components are in the visible part of the spectrum. As unpredictable as it is sudden, this natural phenomenon leaves its mark on those who experience it. The Visible Spectrum is a portrait of five people who survived the impact of the lightning. Each of their experiences is unique in its physicality, its metaphysical dimension or its philosophical meaning. Through the intimacy of their stories, the essence of their faces, voices and bodies, and supported by the meta-media presence of a filmic texture electrified by static charges, this short documentary elaborates a sensible reflection about life when it has brushed so suddenly against death.
