Ghosts of War (2020)

As the Allied armies advance through France in 1944, five soldiers of the United States' 82nd Airborne Division are assigned to guard a chateau. En route to the chateau they ambush German soldiers operating a captured American jeep and leave no survivors. As they proceed with the mission they encounter a group of Jewish refugees. They relieve the American guards at the chateau, who leave hurriedly. Chris, commanding the guard, identifies a repetitive banging coming from the fireplace as a message in Morse code which Eugene translates as "I have no legs".

Eugene finds a journal kept by a German soldier detailing the fate of the chateau's owners, the Helwigs, who were brutally murdered by the Germans for sheltering Jews. The father was burned alive, the daughter was hanged and the son was drowned in a bathtub. As Eugene transcribes another Morse code message, his hand moves involuntarily to spell out the message "If you leave, you die".

A German patrol attacks during the night, and though they are defeated, Butchie is mortally wounded diving on a grenade. The men witness some of the Germans being killed by unseen forces in the same manner as the Helwigs. Before he dies, Butchie rants that what the men are experiencing isn't real and exhorts Chris to "remember".

Convinced the building is haunted, the survivors leave, but repeat the experiences of their trip to the chateau, including the ambush of the jeep and the encounter with the refugees. Believing they're cursed and that their only hope is to bury the bodies of the Helwigs, they return to the chateau. An invisible force hauls Chris toward an outhouse where the Helwigs' remains are revealed.

After burying the bodies, Eugene consults the journal, finding the text is no longer German but Arabic and that the Helwigs were Afghan. The men are then attacked by spirits, one of which tries to drown Chris. The shock of the experience induces hallucinations and when he revives he's being attended by doctors in a futuristic hospital, surrounded by his badly injured and unconscious comrades. Doctor Engel and his staff inform Chris they had been experiencing a simulated reality based on World War II intended to help soldiers suffering from post-traumatic stress disorder.

Chris realizes he and his men are not fighting World War II but are soldiers of the present-day American military. Their final mission in Afghanistan was to evacuate a family called the Helwigs, who had been collaborating with the Americans, before an Islamic State patrol ambushed them. Ordered to hide by their CIA handler, they watched as the Helwigs were slaughtered in the manner witnessed in the simulation. As the men left, the despairing mother of the family detonated a suicide bomb, and with her dying breath uttered the word "Vetrulek", an ancient curse forcing its recipients to endlessly relive their trauma.

The hospital's power fluctuates, confusing the medical staff and convincing Chris the curse is real. The spirits of the Helwig family now haunt the simulation that the men are experiencing. Chris tells the staff the only way to lift the curse is to confront the family, apologise and atone for their sins, and insists on returning to the simulation. While the medical staff prepare Chris' reconnection, they discover the mainframe computer is deleting the patients' memory. They warn Chris just before the countdown to the link reaches five seconds. The timer reaches zero and Chris awakens where his simulated experiences began, in a night-time bivouac with his comrades while a figure watches from the shadows.
