Sensual Dragon Lady Carney (Evelyn Brent) poses as a simple geisha during the day, but commands the Tong´s crime army by night. She and her men hold Chinatown in a stranglehold of opium, vice and contraband. Bribery and assassination keep the local politicians at bay. When the Tong draw unwanted attention from the local newspapers, Carney seeks a patsy to take the fall for her gangster syndicate. She settles on notorious ex-con Gallagher, who, fresh from his release from prison, heads west to join forces with the Tong. What Carney does not know is that Gallagher has been replaced by a look-alike undercover FBI man. As Carney and Gallagher plan their elaborate doublecross, the fate of Chinatown hangs in the balance.
