Following her sister Wadatawi's disappearance, Jax (Lily Gladstone) calls the local sheriffs, but finds out because Wadatawi lives on a reservation, it's not the jurisdiction of the local police and she needs to call the feds. Jax arranges searches herself, but they're unable to locate Wadatawi.

When the state comes to take Wadatawi's minor daughter Roki, Jax kidnaps her niece and sets out for the state powwow in hopes of keeping what is left of their family intact.
