The War of Resistance breaks out, and Suzhou falls. The head of the Japanese cultural plunder organization, the Oriental Cultural Research Society, covets this secret treasure and uses both threats and inducements to force the two families to hand it over. As the younger generation of the Fang and Huang families, Fang Yuanzhou and Huang Zhiwei, try to protect the secret, they face the ultimate tests of life and death, morality, and emotion. Their choices are starkly different: some pretend to collaborate with the enemy to maneuver behind the scenes, some vow to fight to the death, and others try to move the treasure to safety... The struggle is rife with espionage-style wits, sacrifice, and betrayal.
