How do you catch a fugitive who has nothing to lose? US Marshals Madison James and Jonas Quinn have orders to transport two high-profile prisoners across the country on a private plane. But when the plane experiences engine trouble en route from the Pacific Northwest to Colorado, the pilots crash-land the aircraft deep in the heart of the sprawling Salmon-Challis National Forest. With both pilots and one prisoner dead—and one fugitive on the run—Madison and Jonas must negotiate the rugged and remote backcountry as they track a murderer who is desperate to disappear ... and will do anything to stop them.
