The Scottish Highlands; a sparse, mountainous region some say was carved by the gods themselves. Few places are as untouched as this harsh, prehistoric landscape. It is no place for man.

But nestled deep within the wilderness lies a cottage, and behind that cottage is a hill...

When a group of friends travel up from Manchester and hire the cottage for a weekend of boozy fun, they discover a threat far greater than the harsh landscape and unwelcoming weather.

Something deadly lies upon the hill.

And it's waiting.
