Blood Quantum

In 1981, on the Red Crow Indian Reservation in Quebec, Canada, fisherman Gisigu catches a number of salmon, and observes that they continue to move after being gutted. Elsewhere that morning, Gisigu's son, indigenous sheriff Traylor, responds to a call about a dying dog that belongs to his ex-wife, nurse Joss. Traylor euthanizes the dog by gunshot. He goes to visit Joss, and learns that their son Joseph has been arrested for vandalism in a nearby town and is in jail with his half-brother Lysol. Traylor then visits Gisigu, who shows him the gutted yet moving salmon. Joss's dead dog reanimates in the trunk of Traylor's police car, and Traylor shoots it. Gisigu and Traylor set the dog and the fish on fire.
