Cold Moon (2016)

In a sleepy southern town, the Larkin family suffers a terrible tragedy. Now the Larkins are about to endure another: traffic lights blink an eerie warning; a ghostly visage prowls the streets; and graves erupt at the local cemetery in an implacable march of terror . . . And beneath the murky surface of the river, a shifting, almost human shape slowly takes form to seek a terrible vengeance.
