The most infamous cryptid ever to capture the imagination of the planet.

A man putting his life at risk.

When evolutionary biology professor Dr. Zack Hitchens loses his wife in a senseless accident, he decides to follow her dreams all the way to the roof of the world - the peak of Mount Everest. On the infernal mountain, Zack and his teammates battle sickness, whiteout conditions, avalanches, the oxygen-starved minds of other climbers - and something else. Something primitive and consumed with rage. Something seeking revenge.

Something downright abominable.
