Legendary bush pilot Josie Jonson can't believe her luck when a skilled builder just happens to show up after she purchases land near Prentiss Pond. All Mark Redmond asks in return for building Josie's dream cabin is that he be left alone to homeschool his 12-year-old daughter, Cady.

For Maine game warden investigator Mike Bowditch, the intensity of Redmond's secretiveness is troubling, especially in light of suspicious criminal activity being reported around the area―including rumors of an armed man offering large sums of money in exchange for the location of Redmond and Cady. Josie, though hesitant to violate the trust of her prized builder, eventually agrees to fly Mike and his father-in-law Charley Stevens to the secluded pond in an attempt to protect Redmond and Cady. But hours after landing, the trip takes a dark turn when they witness a horrific murder and are taken captive themselves.

Freeing himself, Mike is forced to set off through the impenetrable Maine forest towards Canada, alone and unarmed in pursuit of a mysterious fugitive. As he navigates a windblown landscape choked with deadfalls and blocked by swollen streams, he marvels at his enemy's bush craft. The killer possesses skills surpassing his own, and Bowditch can't tell if he is the cat or the mouse in this dangerous game. Can Mike Bowditch stop his adversary in time to save the life of a young girl, or will he be forced to watch another innocent soul die?
