Wil Weathers has lost his job and his girlfriend, and dark shadows from the past now threaten to return. A backpacking trip up north might just be a cure for the blues. But while waiting for a late-night bus in a small north woods town, Wil finds a body. When he returns with help, in the form of the attractive Sally, the body has disappeared. This sets into motion a series of disturbing events, which sends Wil into flight to the safety of his big-city apartment. When Sally goes missing, Wil returns up north to find her, only to become the subject of a statewide police manhunt and the target of unknown killers. With no resources and few clues, Wil takes to the woods in a last-ditch attempt to find Sally, on a collision course with an insidious eco-terrorist gang preparing to destroy the lives of millions. Now they want Wil and Sally dead.
