The Relic (1997) - Synopsis

The Chicago Museum of Natural History. The grand opening of the superstition exhibit. And people are dying. It started with a guard, found decapitated in the bathroom, his brains removed. Two kids witness something in the basement, unlike anything they've ever seen before. The prize and joy of the exhibit, a Relic of an ancient demon creature. But is it only myth?

The night of the grand opening, Chicago's finest, including the mayor, arrive for the party. Then the blood falls. The monster attacks. The security system goes off. They are trapped inside. With only one way out, through the sewers below, they must brave the impossible and escape the killer that knows their every move.
