In Paris a blonde amnesiac is tentatively identified as Erika Olsen, the mistress of Chinese ballistics expert Feng Hoh Kung. American and Soviet agents, anxious to elicit rocket secrets, pursue the blonde, while their Chinese counterparts seek to kill her. Hired by CIA chief Douglas to pose as Erika's husband, American actor Mark Girland [Gandler?] hides the woman in a Swiss villa. There she reveals that she is neither a spy nor Erika Olsen, but Erika's sister Christine, and that this elaborate imposture will allow Erika to escape from Peking with Feng Hoh Kung's priceless Black Grape pearl. Together Mark and Christine travel to Hong Kong, where they witness Erika's murder by Chinese agents. Falling from Erika's neck, the pearl drops into the sea.
