A few years after the Anshi Rebellion, the Tubo army invaded the southwest. Gao Shi, the governor of the Tang Dynasty, was at a disadvantage in the battle, and Chang'an was in danger. Gao Shi, who was trapped in the isolated city, recalled his life experience with Li Bai to the eunuch who was overseeing the army.In Gao Shi's memories, he returned to Liangyuan three times, visited the Yellow Crane Tower three times, entered Chang'an three times, and visited Yangzhou twice. Each time he went and left, he witnessed Li Bai, Du Fu, Li Guinian, Ge Shuhan, etc.The turning points in the lives of the sages of the Tang Dynasty, as well as the historical events of the Tang Dynasty from prosperity to decline, such as the Battle of Tongguan and the Anshi Rebellion.

Gao Shi was ordered to quell the Yongwang rebellion, and Li Bai was later imprisoned.Li Bai's wife Zongshi came to ask Gao Shi for help. Gao Shi did not comment and arranged for Li Bai and Zongshi to meet across the wall in Jiangxia.Gao Shi and Zong were in one room, and Li Bai and Shu Tong were in another room.Zong heard the conversation between Shutong and Li Bai, and said to Gao Shi: "I will go back to Lushan for the rest of my life", and left sadly.Li Bai later realized that Zong was next door, but Zong had already left.Li Bai shouted to Zong's boat going away: "Go back to Lushan and wait for me, go back to Lushan and wait for me".At the end of the movie, through the dialogue between Cheng Yuanzhen and Gao Shi, Gao Shi wrote to Guo Ziyi and asked Guo Ziyi to save Li Bai.In the end, Li Bai was pardoned. After Li Bai was pardoned, he still did not give up his ideals.But this time he did not choose to enter politics, but put on his armor and prepared to follow Li Guangbi's army to attack Shi Siming. Unfortunately, he fell seriously ill halfway and never got up to catch up with his dream.
