Quantum physics Professor Howard Birack (Victor Wong) tasks his students with their most unusual assignment yet when a Catholic priest (Donald Pleasence) uncovers a strange and ancient substance in a monastery. As the young scientists investigate, dark entities descend upon the church, bringing representatives of Satan to the Earthly plane. John Carpenter wrote, directed, and co-scored Prince of Darkness as the second chapter in his Apocalypse Trilogy, which begins with The Thing (1982), and finishes with In the Mouth of Madness (1995).
