Archaeologist Ma Jun can glimpse the historical truth in his dreams. He leads the archaeological team of the Shouzhen Museum to trace the lost national treasures - from the ten gilt-bronze Buddhas that were robbed in the Old Summer Palace, to the authentic "Preface to the Orchid Pavilion Collection" that has been lost for thousands of years, and to the thousand-year circulation of Xuanzang's parietal bone relics. Amidst the historical scars of blood and fire, they continued the cultural context with awe and guarded the memory of a nation that should not be forgotten.
