Summary
In August 1966, two electronics technicians were found dead on a hill overlooking Rio de Janeiro, Brazil. They were dressed in formal suits, wearing homemade lead eye masks, and lying side by side without signs of violence. Beside them was a mysterious handwritten note containing precise instructions, including one chilling line: "Swallow the capsule... protect with metal... wait for a signal." More than half a century later, no one knows exactly what happened. In this episode of You Can't Unhear , we investigate one of Brazil's most baffling unsolved mysteries. From secret experiments and spiritual beliefs to UFO sightings and failed criminal theories, every explanation leaves behind new questions. Were the two men victims of an elaborate scam, a dangerous experiment, or something they believed was beyond this world?
