En route they ambush a German-captured jeep, executing the occupants who survive the initial attack, before encountering a group of Jewish refugees.

Chris, the group's commander, interprets a repetitive banging sound coming from the fireplace as Morse code, which Eugene transcribes as saying "I have no legs".

The Germans, having discovered the Helwigs had been sheltering Jews, brutally murdered them by burning the father alive, hanging the daughter and drowning the son in a bathtub.

Convinced that the building is haunted, the survivors leave, only to find themselves repeating the experiences that brought them to the chateau - the ambush of the jeep, the encounter with the refugees.

The shock of the experience induces hallucinations before he finally snaps awake and finds himself being attended to by doctors in a futuristic hospital, surrounded by the mutilated and unconscious bodies of his comrades.

Doctor Engel and his staff inform Chris that what he and his comrades had been experiencing is a simulated reality based on World War II intended to help soldiers suffering from post-traumatic stress disorder.

As the men left, the despairing mother of the family detonated a suicide bomb, and with her dying breath uttered the word "Vetrulek", revealed to be an ancient curse that forces its recipients to endlessly relive their trauma.

Convinced the only way to lift the curse is to confront the family, apologise and atone for their sins, Chris explains this to the medical staff, and insists on returning to the simulation.

Miscellaneous Entertainment's D. Todd Shepherd, Shelley Madison, Joe Simpson, and George Waud are producing and financing the film alongside Colleen Camp.
