Janek is a technician on a climate observation station high up in the German Alps, one of a team of scientists preparing their outpost for visit from the Environment Minister. Their routine is interrupted by a strange discovery; a red liquid pouring from a nearby glacier, melted free from the ice crust that is shrinking with climate change. When the 'glacier blood' comes in contact with the local wildlife, it causes changes that are at first curious, then horrifying.
Soon Janek and his team have their hands full defending themselves and the station against a growing horde of biological monstrosities. Using every tool at their disposal they must learn to work together to survive the onslaught.
