Late at night in Bianjing in the fourth year of Yuanyou, a fire broke out in Sima Guang's old residence. The chest of an unknown charred corpse in the ruins actually contained a broken page of Su Shi's "Dongpo Yuefu". The clues pointed directly to the leader of the Shu Party. In the Kaifeng Mansion Hall, Luo Party leader Cheng Yi took the opportunity to launch an attack, while Cai Jing of the New Party secretly stirred up trouble. The experience of Su Shi's concubine Wang Chaoyun made him suspected of "revenge murder." The blind spot of the book boy Xiaopo's perspective casts layers of fog on the case.
This seemingly simple fire and murder case was actually a conspiracy chess game strangled by the party: the deceased was an old member of Sima Guang who had evidence of collusion between the Luo Party and the New Party. Cheng Yi killed someone to silence him and framed Su Shi. Cai Jing tried to reap the benefits and restore the power of the New Party. The secret of Xiaopo's life experience became a key variable in the case.
Su Shi, who was trapped in the whirlpool, went from being unable to argue at first to peeling off the cocoon to explore the truth. In dealing with various forces, he not only had to prove his innocence, but also to tear away the hypocritical mask of party struggle. When the truth came to light, the conspirators were demoted or dismissed, but the strife in the court never stopped. Su Shi, who saw through the power game, finally chose to stay away from the political whirlpool of Bianjing and went to Hangzhou with his concubine Wang Chaoyun and scholar Xiaopo. In the mountains and rivers of the West Lake, he opened a new chapter of benefiting the people.
