New series. Return of the award-winning documentary following the work of the West Midlands Ambulance Service. Call assessor Shanie, who has just graduated, guides a woman through childbirth over the phone, and a specialised mental health team is sent to help a man showing signs of agitation at a community centre. Meanwhile, a day shift takes an unexpected and very personal turn for paramedic Nat when a 999 call about an unconscious patient turns out to be referring to her teenage daughter, who has taken ill at school.
