Kingfisher Lodge, nestled in a canyon on a mile and a half of the most pristine river water on the planet, is known by locals as "Billionaire's Mile" and is locked behind a heavy gate. Sandwiched between barbed wire and a meadow with a sign that reads "Don't Get Shot!" the resort boasts boutique fishing at its finest. Safe from viruses that have plagued America for years, Kingfisher offers a respite for wealthy clients. Now it also promises a second chance for Jack, a return to normalcy after a young life filled with loss. When he is assigned to guide a well-known singer, his only job is to rig her line, carry her gear, and steer her to the best trout he can find.

But then a human scream pierces the night, and Jack soon realizes that this idyllic fishing lodge may be merely a cover for a far more sinister operation.
