As a child in Montana’s Bitterroot Valley, Ruthie Fear sees an apparition: a strange, headless creature near a canyon creek. Its presence haunts her throughout her youth. Raised in a trailer by her stubborn, bowhunting father, Ruthie develops a powerful connection with the natural world but struggles to find her place in a society shaped by men. Development, gun violence and her father’s vendettas threaten her mountain home. As she comes of age, her small community begins to fracture in the face of class tension and encroaching natural disaster, and the creature she saw long ago reappears as a portent of the valley’s final reckoning.
