This documentary series follows the work of the courageous people who respond to 111 calls. In the course of each ordinary day, the audience will get rare insights into the working lives of these extraordinary people.

Emergency Heroes is the only television series which includes footage from all three services - Ambulance, Police and Fire. It is also the only series to include footage inside the 111 call centre - so that every incident is followed from the fateful 111 phone call, right through the event on the ground, to its aftermath.

A team of eight camera crews, five directors and more than a dozen cameras bring the audience close to the action.

The footage includes interviews with officers from cameras inside each vehicle, the hair-raising point of view from inside the Police's Eagle helicopter, and the grittiness of the police street camera network.

We see operators and dispatchers fielding panic-stricken calls - their calm voices seeking details, while they send professionals to help.

We find out what officers are thinking as they race to respond to a call, never knowing exactly what they'll find at the scene. And we hear the emotion of people who are often at their most frightened and vulnerable, as they tell their stories to those who are there to help.
