To save her sick mother and pay off family debts, impoverished Ella marries cursed Jonathan of Blackwood Manor, who suffers constant ghost torment. They learn occult arts from the hermit Agrippa and run a paranormal agency. After Jonathan’s parents are ritually murdered, they investigate rival occultist Victor and jealous Morgana, only to uncover Agrippa’s plot to sacrifice them for his dead family. Though they defeat him, the pair exhaust their souls and slip into a three-month coma. Waking with no powers, they follow a mysterious key to a realm between life and death, tricked by fake gatekeeper Isadora—the real Consumer demon. Cornered, Jonathan’s sealed primeval darkness awakens for a final battle.
