Vetrny demon / Demon Wind (1990)(CZ)

Back in the distant 1931, in a secluded and weathered farmhouse, the gruesome sight of a crucified body set ablaze sends chills down the spine. But inside the house, a fierce, yet futile battle rages on, as Regina and her husband George, struggle desperately to avert a horde of nightmarish and malevolent demonic spectres from entering into our dimension from an ominous dark doorway. In the present day, after the disastrous event of that horrible day, Cory, Regina's grandchild, riddled with questions and the need to investigate the mysterious death of his grandparents, assembles his trustworthy friends back to the old farm where it all began some sixty years earlier, although, not sure what to expect. However, this supernatural territory is a hostile no man's land, a fact that the team is going to pay in blood in order to find out.
