In this taut ten-minute Spanish thriller, a seemingly ordinary security camera installation turns into a nerve-shredding ordeal for its protagonist. The film follows a meticulous technician who is hired to set up a state-of-the-art surveillance system in a secluded, shadowy apartment. As he works, he becomes increasingly unsettled by the distorted images flickering across the monitors he is calibrating, catching glimpses of movements and figures that do not align with the empty rooms he knows he is alone in. His professional composure begins to crack as the line between what is being recorded and what is real blurs, forcing him to confront a presence that seems to be watching him back through the very lenses he is installing. Directed with a masterful grip on suspense, this short film from Jorge Dorado creates a claustrophobic atmosphere of paranoia and dread, exploring how technology meant to provide security can instead become a window into hidden terror. With minimal dialogue and a relentless focus on mounting unease, Daniel Grao delivers a gripping performance as a man trapped in a tightening loop of surveillance and fear.
