Head to the hills, scour the bush, and dive deep into the caves with a series that takes you behind the scenes of the rescues in New Zealand’s unforgiving outdoors. Go out with the volunteers who put themselves on the line to rescue complete strangers. Host Paul Roy looks at the evolution of rescues from the do-it-yourself operations of the 1960s to today's highly managed efforts. They all have one thing in common – something went wrong and someone needed help.

A typical rescue today is aided by GPS, personal location beacons, agile helicopters and LandSAR rescuers. This is in stark contrast to the 1960s, where rescuers usually came from tramping clubs, they provided their own gear, and could be out in the field for days, it was all very "number 8 wire".

In November 1982, two climbers Phil Doole and Mark Inglis were trapped on the summit ridge of Aoraki Mount Cook at over 3000 metres. Taking shelter in a sparse crevasse near the summit, storms and high winds thwarted any rescue attempts when the pair were declared missing after five days.
