The story opens with our newly married protagonists, Elizabeth and Fitzwilliam Darcy, defending their village from an army of flesh-eating 'unmentionables'. But the honeymoon has barely begun when poor Mr. Darcy is nipped aby a rampaging dreadful. Elizabeth knows the proper course of action is to promptly behead her husband (and then burn the corpse, just to be safe). But when she learns of a miracle antidote under development in London, she realizes there may be one last chance to save her true love, and for everyone to live happily ever after.
