The volume of 999 calls has jumped by 60% in the last generation, with 31 million received in 2011. Filmed 24/7 with police, fire and ambulance teams in Blackpool over six weeks, from the moment calls are received, this documentary series shows how Britain is changing, through the eyes of the emergency services on the front line. The series highlights issues ranging from the damage caused by drugs and alcohol to the reality of domestic violence, and from the dysfunctional way that some people bring up their children to the plight of those who slip through society's safety net.
