Fast-paced, adrenalin-pumping docuseries that shine the “blue light” on our 999 services have never been more popular. And Emergency, which is filmed in London, is back to capture all the drama as it follows the stories of seriously injured patients and the people – consultants, ambulance response teams, doctors, nurses and therapists – helping to save their lives. The series focuses on the work of the London Major Trauma System, a network of trauma units, air ambulances and medics set up in the wake of the 2005 London terrorist bombings to provide specialist care for critically injured patients.
