In 19th century England, society is beset by a mysterious plague that has turned the dead into zombies. Amidst this apocalyptic backdrop, the five Bennet sisters—Elizabeth, Jane, Kitty, Lydia, and Mary—have been trained by their father in martial arts and weaponry to defend themselves against the undead menace. While their mother remains preoccupied with marrying off her daughters to wealthy suitors, the sisters navigate a world where the social mores of the time clash with the necessity to fight for survival.

During a social event, Elizabeth Bennet, the second eldest and most headstrong of the sisters, encounters the wealthy and aloof Mr. Darcy, who is a renowned zombie killer. Their initial interactions are rife with misunderstanding and mutual disdain. Meanwhile, Jane, the eldest sister, catches the eye of Mr. Bingley, a charming and affable gentleman, but the blossoming romance is threatened by both the societal expectations and the growing zombie threat. The complex interplay of relationships is further complicated when the Bennet sisters encounter a handsome and persuasive soldier, Mr. Wickham, who has his own agenda amidst the chaos of the undead.
