Forbidden City restorer Chen Mo is awakened by a mysterious phone call: the missing snake and beast heads from the Old Summer Palace will appear at an underground auction in Paris.
Wearing night clothes, he sneaked into the auction house transformed from a medieval tomb and bought a snake head at a high price during the fight between the rich and the gangsters.
On the way home, he was suddenly ambushed. Chen Mo performed life-and-death parkour on the roof of the Seine. The snake head accidentally triggered the mechanism in the crisis.
The bronze snake talisman pointed to the Bridge of Sighs in Venice. He followed it but was surrounded by the Italian Mafia.
At the critical moment, Irene, a female archaeologist from Cambridge, drove a gondola to the rescue: "Let's cooperate, this map points to the Library of Death in Egypt."
