Homicide detective William Wolfe thought Black River, Iowa, was in his rearview mirror when he tossed his suitcase in his trunk and headed out onto Route 13. Now, after more than a decade, Wolfe returns to help care for his ailing mother, but the road back has some dangerous curves. He soon discovers his birthplace dying from the meth plague. The bucolic ideal and old friends have been nightmarishly transformed. Not immune from his own addictions, he confronts the violent forces bringing disease, death, and disorder to those caught in the middle.
