Savageland

Savageland is a 2015 American mockumentary horror film written and directed by Phil Guidry, Simon Herbert, and David Whelan, concerning a massacre on a US-Mexico border town that leaves every citizen dead except for an amateur photographer who is accused of committing it.

He also falls under suspicion after being accused of having an inappropriate relationship with Grace Putnam, the young daughter of religious missionary Duane, who is a friend of Salazar's; other residents acknowledge the dynamic was innocent.

Salazar refuses to speak and, despite contradictory evidence pointing to it being impossible that he committed the murders—a lack of motive, the difficulty of killing so many residents in a single evening, and the fact that he himself has the same bite marks as the victims—he is found guilty and sentenced to death by lethal injection.

Salazar photographs a number of disturbing images of violent, contorted zombies attacking, devouring, and turning residents before attempting to make his way to the church to find the Putnams.

After the Border Patrol specialist warns that Salazar's evidence indicates that the horde of zombies is steadily moving north, and Sangre De Cristo was merely in the way, it is revealed that mysterious deaths and disappearances have been recorded hundreds of miles away from the town.
