When you do this job well, you can save more than the lives of your patients.
 
William Marshall, emergency medical technician with Mountain EMS, struggles with his past and with a desperately understaffed service while providing patient care in Banff National Park. Highway wrecks, medical responses, and backcountry disasters are standard fare. Marsh, as he likes to be called, coaches new-hire Miranda Walker through the learning curve while the crew answers to an overbearing medical director. With the impending threat of a fire department takeover of their service, Marsh and Miranda confront public and private emergencies with professionalism, courage, and humour.
 
Against the odds, they turn their service and each other’s lives around.
