Upon release, Season of the Witch was met with largely negative reviews from critics. It currently holds a low score on Rotten Tomatoes, with critics citing a lackluster script, uneven pacing, and a tonal confusion between serious historical drama and B-movie horror. However, in the years since its release, the film has garnered a cult following among fans of Nicolas Cage, who appreciate the film's campy elements and the actor's signature intense performance style.

Upon returning to Europe, they find the land ravaged by the plague. They are quickly recognized as deserters and captured. However, Cardinal D'Ambroise (Christopher Lee, in one of his final roles) offers them a pardon on one condition: they must escort a young woman (Claire Foy) accused of witchcraft to a remote monastery. The Church believes her witchcraft caused the plague, and the monks at the monastery possess an ancient ritual book capable of lifting the curse.
