That looks ... Interesting. If I remember correctly, among the many theories postulated for the plague at the time, witchcraft was pretty prevelant. So the story is plausible, even if they are mixing time periods. I think in one of the scenes, I saw masks worn by plague doctors which I believe did not appear until the 1400's, but I may be off on that. I'll probably wind up seeing it at some time or other because of the theme and Nick Cage is in it. For some reason, I like him, one of the few actors that I generally like their work.
