Cameras capture the work of some of Britain's busiest Air Ambulance teams as they race against the clock to save lives in the golden hour; from dramatic mountainside rescues to roadside emergencies, the Heli-Medics battle to help those who need it.

In Hartlepool, the heli-medics are tasked with treating a man hit by a train; cyclist Trevor suffers serious injuries after a collision with a car; motocross biker Arai in Cumbria is flown across the country for emergency surgery.

Chris suffers multiple injuries after a quad bike accident on a farm near Penrith; cyclist Vivienne is in a bad way after her bike leaves a notorious Cumbrian pass.

In Cambridgeshire, the heli-medics race to treat a cyclist with a time-critical brain injury; on the Norfolk Broads, Tom breaks his thigh bone jumping off a boat; Cedric, an 87-year-old pilot, is put into an induced coma.

In Hertfordshire, the heli-medics help a man fighting for his life following a cardiac arrest; a tumble on an obstacle course leaves fun-runner Vijitha with a painful open fracture; 7-year-old Imogen suffers an impalement at the bike track.
