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.
