In Miaoling Village, the fertility cave was said to grant babies, yet no infants were born for a whole year. The village chief picked the female lead as the cave goddess to soothe divine wrath. Her younger sister snuck into the cave, met the male lead, and they investigated together. His sister died by suicide mysteriously after praying for a child. They uncovered the truth: the chief used narcotic incense for profit and abandoned baby girls. The female lead secretly protected village women and sheltered abandoned infants. At last, the trio exposed the plot, brought the chief to justice and destroyed the cave.
