Set in 19‑century Wallachia, vampire prince Vlad Dracul is fatally wounded. Human doctor Elena with holy blood saves him, yet she is exiled and reported dead by conservative elder Agatha. Seven years later, blinded by a holy‑water curse, Elena survives in slums with her holy‑blood twin children. Vlad tracks them down and faces false charges, rebellion and dungeon perils. After overcoming plots and racial prejudice, Vlad marries Elena as his princess‑consort, and the family regains rule over the duchy.
