A young single mother of Dai minority named Ye Nan returns from Shanghai to her scenic home village at Sino-Burmese border. She tries to assimilate back into her clan and make amends for the tense relationship between her and her daughter, Nan Hang. During one of their quarrels, the rebellious teenage girl rants questions about why one must relocate to cities to compete for the best colleges and jobs rather than stay in their countryside ancestral homes and farm for a living. Reflecting on a series of setbacks, Ye Nan gradually gives in to learning about Nan Hang's life instead of disciplining her. After Nan Hang's partner-in-crime schoolfriend who's also a left-behind child passes away from untreated illness, the villagers believe they're influenced by a devil and decide to perform a ritual to worship the local stone Buddha. As they dance outside the 250-million-year-old karst cave temple, whose gate is closed for non-business hours, a plane flies across the sky above them, and Ye Nan sees an opportunity to reconcile with her daughter.
