In the small town of Feymont, Minnesota, all that anybody has to look forward to that week was a little sun. But, like every town, Feymont has it's fair share of secrets, and the nuclear plant (that has been upholding the local economy since the founding of the town) harbored most of them.
One fateful Saturday, all of the plant workers are called into work. They never come back.
Strange things begin happening in Feymont. Bodies found, mangled. Incident reports, sightings of creatures only before seen in nightmares. Endless howling, all night long.
When the people of Feymont finally discover what is going on, it is already too late.
