Derek Harrington, retired Marine Force Recon and SERE instructor, is barely scraping by teaching the basics of wilderness survival. His fledgling bushcraft school is on the cusp of going out of business and expenses are piling up fast.

When one of his students presents him with an opportunity too good to be true - $20,000 to instruct a private group in upstate New York - Derek reluctantly takes the job.

But it isn't long before the training takes an unexpected turn, and soon Derek finds himself in deep cover embroiled with a fringe group led by a charismatic leader who will stop at nothing to get what he wants.
