Patriots headed by Yan secretly sneaked into Shanghai and formed a falcon assassination team with six other people with special skills. It is their duty to deal with the Japanese puppet government skillfully and get rid of the unrepentant traitors, thus preventing the Japanese from plundering China's wealth again and again. Sent by Japan's economic intelligence agency, Takeo Imai, the special envoy of the Japanese Emperor, came to Shanghai to buy China gold with counterfeit money in search of the treasures left by the Taiping Heavenly Kingdom. Through the mouth of the mayor's daughter, Yan got the top secret news, set a trap with Zheng He and Lin Xiaojiang, pretended to be a Japanese prince, hijacked the gold jewelry that Takeo Imai was going to transfer to Tokyo, framed the gang leader, and got rid of the gang traitor by the hand of the police chief, and successfully transported the treasure to the base area.
The plan was hit hard, and Beowulf was furious at Imai, and sent a beautiful spy to infiltrate it. However, deeply admired by him, he secretly sent a message to Yan, telling him that Takeo Imai had a secret counterfeit money factory in the countryside, and they used counterfeit money to buy China materials.
Later, Yan was arrested and beaten. He refused to tell the whereabouts of the treasure and ran away. He found this treasure with Yuexin Zhang, Yan Yunyao and his falcon assassination team, but after going out, he fell into the hands of Beowulf Imai again. There is a traitor in it. Who could it be? Neither Zheng, Yan Yunyao nor Mu can believe these people around them.
