During the Republican era, the Yin family holds a 'joy-bringing wedding' for their deceased eldest grandson, Yin Zhan Ting. Su Qingyin—the original bride from the Su family—terrified of being buried alive as a sacrifice, flees her wedding night. Grandma Su burns incense and summons a fox spirit, Lady Hu San Tai Nai, who once received kindness from the Su ancestors. Lady Hu San Tai Nai agrees to possess Su Qingyin's body and marry into the Yin household in her likeness—using immortal powers to revive Yin Zhan Ting.
