The Adirondack National Forest is vast, thousands of acres of untouched land. Michael and Karen hope to spend a pleasant weekend together, hiking, camping and relaxing in his uncle's cabin. But after a series of unfortunate events, the married couple will find their cabin under siege by something that should not exist, something only spoken of in playful fun around campfires. Forest Ranger Laura Carson is new to the Ranger service, and when she sees the cabin and what has happened to it, she can barely maintain her composure. It looks like a grizzly bear attack. With a big city police detective by her side, she and a group of Forest Rangers will travel deep into the mountains to search and destroy the rogue grizzly bears before others can be hurt. But it wasn't grizzly bears that came upon the cabin and the frightened couple hiding within, it was something unimaginable. Laura will soon find herself in a life or death situation, fighting for survival against creatures that should not be, one where monsters of legend attack with fury, wanting nothing more than to protect their home from invasion from the outside world. When man and myth collide, blood will be spilled, and the Clan of the Bigfoot will finally be exposed. But the question is: will there be any survivors to tell the tale?
