Doyle, recuperating from knee surgery, rushes back to the mountains of California in a desperate search for proof that Colonel Miller survived the brutal onslaught. Failing to find the answers he seeks, he swiftly resumes his search-and-rescue duties in the Great Smoky Mountains, all the while anxiously awaiting orders from The Patriot's Group. Jonah, one of Doyle's superiors, abruptly assigns him a search mission in the Crazy Mountains, Montana. However, before Doyle can even set out, Senator Douglas launches a shocking attack, kidnapping Doyle's father, Barry Anderson. The Senator whisks Barry away to his remote ranch in Wisconsin, where he plans to subject him to unspeakable torture and ultimately execute him. Jonah is left with no choice but to redirect Doyle's mission to a daring rescue operation. Doyle's long-standing adversary, Colonel Miller, suddenly resurfaces, bringing with him a trove of long-buried secrets. This high-octane adventure, unfolding on three distinct fronts, hurtles towards a climactic showdown in Wisconsin.
