Ghosts of War (2020)

During the darkest days of World War 2, five battle-hardened soldiers are assigned to guard a Chateau deep in the French countryside formerly occupied by the Nazi high command. Cut off from contact with the outside world, the group begins experiencing inexplicable events and are ruthlessly tormented by unseen forces – something else is in the house that will not let them leave alive. As their situation spirals into horrifying madness, a last-ditch effort to escape reveals a twisted modern-day nightmare even more terrifying than the evil forces hunting them for revenge.
