A predator stalks the frozen woods.

At a fort deep in the Ontario wilderness in 1878, a ghastly predator is attacking colonists and spreading a gruesome plague—his victims turn into ravenous cannibals with an unending hunger for human flesh. Inspector Tom Hatcher has faced a madman before, when he tracked down Montreal’s infamous Cannery Cannibal. But can even he stop the slaughter this time?

In Montreal, exorcist Father Xavier visits an asylum where the Cannery Cannibal is imprisoned. But the killer who murdered thirteen women is more than just a madman who craves human meat. He is possessed by a shape-shifting demon. Inspector Hatcher and Father Xavier must unravel a mystery that has spanned centuries and confront a predator that has turned the frozen woods into a killing ground where evil has come to feed.
