We join the staff of the London Ambulance Service on a Monday morning. Forty-seven call handlers are on duty to answer emergency calls from across London. Control will be dispatching 325 ambulance crews across the capital whilst they also prepare for an estimated 30,000 Extinction Rebellion protesters who will take to the streets over the coming days.

Each year, the London Ambulance Service trains 120 new emergency call handlers. We join Amy, who is less than a year into the job, as she tries to get help to a patient who has been assaulted by her partner. The woman is unable to tell Amy her proper addres, which means the team on the ground have difficulty locating her.

As the shift moves into the afternoon, the number of emergency calls coming into control has doubled and protesters have brought parts of London to a standstill. A 999 call for a baby having a fit is a priority call, and crewmates Kate and Terry are immediately dispatched. They are 2.5 miles from the Category One emergency, but the traffic jams lead to a fraught journey for the crew.

Later, in control, Amy takes a 999 call for a patient threatening to set fire to a building, and trainee call handler Mackenzie, who is on her final shift of training, is put to the test when she takes a call from a woman in late-stage labour with twins.

As the busy afternoon progresses, multiple 999 calls are received reporting that a 15-year-old boy in school uniform has been stabbed. The news is not good and knowing they can not save him from his fate has a profound effect on the team on shift. Show less
