Desc: The Son-Daughter: Directed by Clarence Brown, Robert Z. Leonard. With Helen Hayes, Ramon Novarro, Lewis Stone, Warner Oland. A large group of Chinese immigrants in San Francisco is clandestinely donating whatever money they earn to smuggle arms into China for the rebels in their fight against the centuries old Manchurian imperial oppressors. The secrecy of their mission is to hide their identities from anyone supporting the imperial regime. One of the immigrants supporting the rebels is Dr. Dong Tong. His only offspring, the demure Lien Wha, who also supports the cause, is in love with poor university student, Tom Lee, the two who, after meeting formally, want to get married, which Dr. Tong supports. However, Dr. Tong learns that the rebel backers are short $100,000 for the latest shipment of arms, and are asking the four men within the group with eligible daughters to donate $25,000 apiece, that money to be raised by selling their daughters into marriage to a wealthy buyer. Dr. Tong is one of the four, Lien Wha the daughter to be sold. Simultaneously, Dr. Tong learns of Tom's true identity as the son of one of the most important leaders of the rebel movement in China. Dr. Tong's answer to the request not only threatens Tom and Lien Wha's marriage plans and happiness, but also the arms shipment and all their lives.
