Elemental Alvin Zhu and mafia boss Zachariah Wong try to save Lily, Zachariah's daughter, from dying. Unlike Zachariah, Lily can't shield herself from being possessed by spirits of the dead, who feast on her life energy. Alvin uses his elemental power to remove the spirits and defend Lily from them, but it seems futile. The number of spirits increases in spite of his protective shield around their residence. The condition also worsens after Linda, Lily's mother, visits the house. Meanwhile, as time passes by, the two men's feelings for each other grow stronger while Lily grows weaker. Alvin asks Camden, an incubus and an old friend, for advice and a permanent solution to Lily's problem, but the incubus's cryptic message is driving him crazy. Then, Lily disappears from the house. Can he and Zachariah find her in the nick of time? Can they solve Camden's riddle and resolve Lily's problem once and for all?
