New York, Christmas Eve, 1999 - at the dawn of the new millennium - a subway construction crew unearths an eight-hundred-year-old Celtic skeleton and a mysterious key. Archeologist Karen Goodleaf is called in to determine the meaning of the discovery.
News of the discovery reaches a Middle East monastery where the warrior monks known as the Knights Templar - an ancient sect entrusted with protecting holy relics - choose their best pupil, Lukas (Dolph Lundgren) to face the diabolical threat. As Lukas races to New York, an evil Minion seizes Karen and uses its body like a parasite and host.
Lukas arrives just in time to rescue Karen and dispatch the Minion. The Minion takes hold of another host - revealing that it is immortal. As it cuts a path of destruction through the city, decimating a parking garage and leaving a trail of death, Karen realizes that the Minion can't be killed - but only delayed from finding a new host.
