Chen Yan, a special soldier in the army, witnesses the appearance of a mysterious animal head at an auction in London, followed by a bloody assassination.
He was framed as a murderer, and while on the run, he met a strong Chinese girl and an Egyptian scholar who was proficient in cracking.
The three of them followed the clues to the black market in Cairo and accidentally discovered that the animal head actually contained a star map pointing to the lost national treasure in the Old Summer Palace.
Going deep into the underground secret room of the Valley of the Kings, they encountered the siege of the international cultural relics gang "Dark River".
