It's been two months since private investigator Cal Weaver's teenage son Scott died in a tragic accident. Cal is mired in grief, and maybe that has clouded his judgment. Driving home one night, he makes his first big mistake. A girl drenched in rain taps on his car window and asks for a ride as he sits at a stoplight. Even though he knows a fortysomething man picking up a teenage hitchhiker is a fool, he lets her in. After a brief stop at a roadside diner, Cal senses that something's not right with the girl or the situation, but it's too late. Something is horribly wrong in the small town of Griffon in upstate New York, and when Cal decides to expose those secrets, one by one, that's his second big mistake.
