This landmark UKTV Original documentary series follows the work of one of 16 specialist medical units set up after the 7/7 London bombings to treat badly injured patients in extreme environments - and has granted unprecedented access to its daily life, highlighting the camaraderie and courage of the men and women in the Hazardous Areas Response Team of the Yorkshire Ambulance Service, who risk their lives to save ours.

They are trained to enter burning buildings, deal with the victims of terrorist attacks, brave toxic gas clouds and abseil to the rescue down cliff faces. The 10- part series will also capture the banter in the mess hall and the blood sweat and tears of a training regime. The team's advanced medical capabilities allow them to perform surgical procedures in a range of locations from the street to the cramped confines of a collapsed building or down a Pennine pothole, keeping patients alive long enough to reach specialised medical care.
