One hundred years ago, an angry mob, intent on justice for their murdered children, hang the woman they believe is the murderer. They brand her a witch, wrap her body in chains and bury it deep in the woods. Flash forward to the present - when Deb and her friends play a childhood game on the witch s wooded grave, they open the door to death. As her friends and family begin to change into something less than human, Deb struggles to stop the witch s curse. But her search for the truth will reveal an evil beyond her imagination.

14th-century knights transport a suspected witch to a monastery, where monks deduce her powers could be the source of the Black Plague.
