Deep beneath the two-century-old library building of Graebner College, in the bucolic town of Covington, Vermont, Sam Whitney and Lenore Simensen come upon an ancient medieval ritual called The Code. With it, they are able to predict where financial markets are going. Vast sums of money are made. Everything is perfect - perfect until something very dark and very dangerous is unleashed. Unaware of what is happening to her, Lenore starts on a rampage of killing. Katy Malone and Nick Sanchez, two ace students at Graebner, discover what Sam and Lenore are up to. All find themselves trapped in a deadly web spun by The Code. In the end, during one of the rituals Sam Malone kills Lenore when she comes after him with a knife deep in the underground chamber. In the last chamber we learn that the evilness is not gone; it is merely transformed to Sam. It will continue.
