We investigate how a humanitarian tries to survive the inhumane flaming pit of a volcano; discover how a couple of isolated hunters handle a deadly role reversal; learn how an urban free climber turns harmless hangouts into near death experiences; witness an adventurer taking on his biggest but coldest challenge yet; see how a vet copes faced with an impossible decision and we go up a hostile hang out, 7,000 meters above sea level. Plus, there are loads of clips from around the world illustrating just how hostile hang outs can be.
