Daughter of Shanghai

Six aliens are being smuggled on a plane by Frank Barden and Andrew Sleete, but they're pursued by a government plane. They dump the aliens into the ocean and later try to sell some to a wealthy merchant, Quan Lin, who refuses. After his murder, his daughter Lan Ying Lin seeks help from Mrs. Mary Hunt, a society matron who introduces her to a government agent, Kim Lee. However, Mrs. Hunt is actually the mastermind behind the smuggling ring.
