Three filmmakers spend the night in a haunted forest to shoot a documentary about the legend of Grete Müller, a woman convicted of witchcraft and burnt at the stake over 300 years ago. Coined as the "Blair Witch" of Germany, "Raw: The Curse of Grete Müller" is the first film in the Raw trilogy-a found footage film series from Germany, released for the first time in the United States and UK.
