This three part documentary series had exclusive access to London Fire Brigade (LFB) over one year as they responded to a staggering range of emergencies.  It provides a unique insight into their work, with firefighters filming themselves on the dangerous front line using special fire cameras.  It is access on an unprecedented scale to incidents across the whole of London, with the brigade dealing with around 20,000 fires a year, as well as incidents such as traffic accidents, floods, and other rescues.

The series includes firefighters talking for the very first time about the Grenfell fire and their experiences of that tragic night. The Grenfell Tower tragedy shook Britain to the core and on the front line of the disaster were the heroic firefighters of the LFB.  It brought to the fore an emergency service who risk everything to help those in need.

The documentary also follows the LFB respond to the Croydon tram crash where 7 passengers lost their lives. The film shows the affect this has on the rescuers and how they deal with the trauma amongst themselves.
