Lily Gladstone excels in this tale of stoicism and family, a drama that highlights the still existing ambivalence of the authorities to the Native American population. It's structured as a mystery and road movie although this is about relationships as much as anything else. Gladstone is Jax, who lives on an Oklahoma reservation, caring for her teenage niece, Roki (Isabel Deroy-Olson) since her sister and Roki's mother has disappeared. The police have treated the disappearance lightly and Jax, who still hustles and deals drugs, is ever trying to find some clue to her disappearance. When her white father (Shea Whigham) files for custody of Roki they head out on the road to reach an Indian festival, a powwow, where they hope Roki's mum will turn up. This theme of disappearance reflects the American tendency to be blind to its Native Americans and treat them as less worthy of support and aid as others. It's a moving film that has the odd misstep but its strong performances and thoughtfulness make it a serious and interesting drama.
