Summary: Jarvis stars in his own horror movie, exploring the battle between the forces of darkness and light. He hears from horror movie goers at the Electric Cinema in Birmingham, keen to turn the lights off and lets the scares begin; the National Grid control room which is charged from keeping the lights on; and Lundy Island in the Bristol Channel - where the electricity switches off at midnight. What is lurking in the basement as Jarvis approaches the darkest hour? Producer: Laurence Grissell
