What Is It?
The 2021 / 2022 movie The Cursed.
Here is how The IMDb describes this movie:
In rural 19th-century France, a mysterious, possibly supernatural menace threatens a small village. John McBride, a pathologist, comes to town to investigate the danger – and exorcise some of his own demons in the process.
In the late nineteenth century, brutal land baron Seamus Laurent slaughters a Roma clan, unleashing a curse on his family and village. In the days that follow, the townspeople are plagued by nightmares, Seamus’s son Edward goes missing, and a boy is found murdered. The locals suspect a wild animal, but visiting pathologist John McBride warns of a more sinister presence lurking in the woods.
