Years had gone by, Qiushui married Jindi and settled in Tibet. While in Taiwan, Biyun buried Qiushui's mother and continued to pray for his return. Flashback to modern time, Biyun is living in New York. Her niece played by Isabella Leong, a writer, has travelled to Tibet to find out what happened to Qiushui.
