A truffle hunter who lives alone in the Oregon wilderness must visit Portland to find the mysterious person who stole his beloved foraging pig.

After Portland homicide detective Nick Burkhardt discovers he's descended from an elite line of criminal profilers known as "Grimms," he increasingly finds his responsibilities as a detective at odds with his new responsibilities as a Grimm.

After learning that a boy their age has been accidentally killed near their rural homes, four Oregon boys decide to go see the body. On the way, Gordie, Vern, Chris and Teddy encounter a mean junk man and a marsh full of leeches, as they also learn more about one another and their very different home lives. Just a lark at first, the boys' adventure evolves into a defining event in their lives.
