 Greenloop is the perfect eco-friendly community located in the forests of the Pacific Northwest before it becomes the site of a massacre that is too mysterious to explain. Following the eruption of Mount Rainier, the isolated community becomes the hunting ground for a creature that has long been dismissed as an urban legend. Told through the journals of resident Kate Holland, the days leading up to the massacre are marked by fantastically large footprints, strange sightings, and gruesome deaths that all seem to point towards one unbelievable thing, Bigfoot.
