At its core, "Wind River" is a film about the devastating consequences of trauma and the ways in which it can both unite and isolate individuals. Jane's investigation into the murder of the young woman, Natalie, serves as a catalyst for her own exploration of grief and loss. As she works to unravel the mystery of Natalie's death, Jane is forced to confront the traumatic events of her own past, including the death of her husband in a hunting accident. This convergence of past and present, personal and professional, allows Jane to slowly begin to heal and find a sense of purpose.
