The Tunguska Event

1908 - The Tunguska event. When a meteorite skips across Earth's atmosphere over Siberia, the resulting explosion flattens trees and shakes buildings over hundreds of kilometres. A small fragment breaks free of the larger meteorite and crashes to Earth on a remote Siberian farm. When the farmer investigates the damage to his crops and property, he discovers a crater in the floor of his barn. In the centre, a large piece of rock, a meteorite. Suspecting there is money to be made from selling it, remuneration for the damage it had caused, he takes it to the nearest museum, setting the fragment on its path across the European continent.

1934 - After years on display, a Russian scientist accidentally discovers the meteorite's hidden payload: alien lifeforms, dormant and barely alive. To study them, a team of scientists set up a secret laboratory beneath the streets of Minsk.

1941 - They have barely begun to understand the amazing properties of the alien organisms when the German forces invade and discover the hidden laboratory. They seize its contents and move them to a specially designed underground complex in the Bavarian mountains.

1945 - Allied forces invade France and drive back the German forces. With their enemy closing in on the lab, the scientists rig it with explosives to hide the evidence of what went on there. Shortly before the entranced is sealed, soldiers arrive with a truck laden with plundered treasures.
Though trapped with no ability to escape, the aliens survived passage through the vacuum of space, they could survive this. They remain alive beneath the Earth, waiting.

Present day - A treasure hunter finds mention of the Bavarian facility in a secret file while looking for information on lost Nazi gold. His previous research already hinted that there might be a huge cache of gold in the area, this secret subterranean bunker would be the perfect place to hide such valuables. After coaxing his wife, Tess, to accompany him, they set off to find the facility and what it might contain.
Inside, they find their greed for gold has ensnared them in a horrifying nightmare they might not escape from.
