Ok so it sounds somewhat similar to JJ Abrams Revolution but we can assure you that Channel 4's new feature length drama is NOT Revolution 2.0. This one-off explores what might happen if Britain's national electricity grid were to be disabled by a devastating cyber attack. The programme makers make use of a combination of real user-generated footage, fictional scenes and TV footage to add a chillingly realistic element to proceedings. We certainly hope nothing similar ever happens here...
