Congenial, unassuming, Adam Thompson's job is to scour the countryside to identify weeds that must be destroyed. Around his hometown, he is well-received. When he ventures into a remote corner of the county, he meets the Hudson brothers and learns routine friendliness is not always the way of things. He becomes an unwitting focal point in the county's crime of the decade. The story winds its way through a small town in Nebraska to Mount Rushmore to Rodeo Week in Stampede, Montana, and back again. It's a raucous, unpredictable journey, which underscores the importance of change, the influence of family, and the risk of squandered human potential. A scarred eyebrow becomes an ever-present reminder of Adam's run-in with Rufus Hudson and his brothers. His granddaughter runs her fingers over his dented eyebrow and asks if the scar will that ever go away. ""No,"" he answers. ""It's just a part of who I am. A very important part, I think.""
