After viewing the summer solstice at sunset from Oregon's Larch Mountain, John and Sara Todd's car is run off the road while navigating the scenic highway on their way home. The driver, barreling down a long gravel driveway from an abandoned sawmill doesn't stop. John and Sara wonder - why didn't he stop? Who owns this property? What was he doing up there?As they track down the person who wrecked their car, they stumble into a case of illegal dumping of toxic waste and a desperate business owner. The Todds stay a step ahead of the DEQ, local police, and FBI but as they put together the missing pieces they find themselves dead center in the cross-hairs of a man with nothing to lose.
