Ye Nan, a mother belonging to the Dai minority, comes back to her village after living in the city. She wants to take care of the 13-year-old daughter she'd left behind, but the road to rebuilding their relationship is full of obstacles. One day her daughter is arrested for stealing money from the village's most sacred temple with her friend. Since people think the girls are possessed by the devil, they decide to save them by worshipping a stone Buddha in a 250-million-year-old karst cave during the Water-Sprinkling Festival.
