Archaeologist Agnes Hsu-Tang investigates the Nanyue King's Tomb in Guangzhou, where excavators found a jade burial suit, a funerary honor supposedly reserved for Han emperors. No historical record names an emperor entitled to that burial in this region, so the film works through who the occupant actually was and what kingdom he controlled on the empire's southern edge. A second case takes the story to Anyang in Henan province, where a tomb discovery provoked argument among archaeologists over whether it belonged to Cao Cao, one of the most contested figures of the Three Kingdoms period. Hsu-Tang walks through both excavation sites, examines grave goods and inscriptions, and talks with researchers weighing the physical evidence against the historical record. The film uses these two burials to open up a wider picture of the Han dynasty's reach and the Three Kingdoms era that followed it, treating each tomb as a puzzle with real archaeological stakes rather than a settled story.
