What would happen if a devastating cyber-attack hit the national grid?
New television drama Blackout explores what would happen during a digital apocalypse. The Channel 4 show will follow the events as police and hospital try to deal with the fallout.
The footage will be made to seem very life-like, as it was filmed on mobile phones and hand held cameras, mixed with footage recorded during real power cuts and other emergencies.
Director Ben Chanan said: "I'm delighted Channel 4 have commissioned such a bold and experimental programme, cross-cutting actors with video bloggers, shooting drama on mobiles, taking an anarchic approach to filming Britain in anarchy."
Nick Mirsky, Channel 4's deputy head of Factual, said: "This is completely new and innovative way to dramatise our total dependence on electricity by asking what would happen if Britain were to be plunged into darkness - not for a few hours, but for five days."
