The airmen and paramedics of Air Zermatt, an alpine search and rescue team, work in perilous conditions to recover those in need of help while climbing Switzerland's Matterhorn mountain.

The Matterhorn and surrounding mountains can be treacherous, but for rescue service Air Zermatt it's home; as rescue veterans, the team have learned to put their emotions aside to get the job done.

During a rescue, lead pilot Sam senses something wrong with the helicopter and must decide whether to land; a life-or-death situation in the Air Zermatt hangar tests the skill of medics.

When a major storm shuts operations down, an isolated hiker must find his own way out of a dire situation.

Technology has come a long way since the original Lama helicopter, and Air Zermatt has revolutionized mountain rescues by making journeys safer and more efficient.
