A retired mountain climber, Ward Donovan (Aaron Douglas of BATTLESTAR GALACTICA) is hired by a rich guy to rescue another group, which includes his ex-wife.
There are weird creatures that live on the mountain, presumably of alien-origin since it's hinted by one of the guides that "the gods" fell from the sky long ago and took residence on the hunk of rock. This is also ties into the origins of the mythical city of Shamballah, where people don't age. This turns out to be a side effect of these weird larvae. The healing property is in their blood, though they are also carnivorous and feed like piranhas.
As Syfy monster movies go this is leaps better than any Crocosaur or Octoshark movie. The story is interesting, the actors are a step above and the cgi creatures don't disappoint. Recommended.
