During the Republican era, young Lin Hao fails at thirty blind dates—until he meets the mysterious Su Wan and falls for her at first sight. Su Wan behaves strangely because she is actually a wronged spirit who died with her grievances unredressed. She has only seven days, and needs a sincere kiss to temporarily keep her soul in this world. Unafraid of the divide between human and ghost, Lin Hao kisses her to sustain her life. Mo Chen, the scoundrel who caused Su Wan's death, and Chang Qing, a sinister cultivator who wants to devour her soul, come hunting them. Lin Hao joins forces with Xuan Qing, a bumbling Daoist priest, and ventures everywhere in search of rare medicines. After many dangers, they destroy the evil forces, gather all the ingredients, and complete the resurrection ritual. Su Wan regains her mortal body, and the two transcend life and death to finally be together.
