Ambulance focuses on the stories behind the sirens during the service’s busiest summer ever, by simultaneously showing the work of the crews on the road and staff in the control rooms who answer over 4,000 emergency calls every day.
The documentary, narrated by Christopher Eccleston, was filmed with crews based in Greater Manchester between May and July 2018.
Each episode in the eight part series focuses on the work of ambulance staff and the patients they treat during one particular shift.
Ambulance starts on BBC One at 9pm on Thursday 18 October.
