Human bones are found at the Garizmendi farmhouse. Farmers Fermin and Karmen call their son Nestor, who reports the matter to the authorities. But, when the agents turn up, the bones are gone. Suddenly, the bell on the nearby chapel begins to peal. This bad omen announces the coming of tragic events and reopens old wounds within the family and those around it.
Unfortunately the movie Death Knell is not yet available on HBO Max.
