The attempts of four secret agents to get a scientist's widow to share her husbands secrets form the basis of this comedy. The rival spies come from France, Russia, Switzerland, and Germany. The woman presents a real challenge as she is a retired stripper (her husband died in a brothel). All of the spies attempt to seduce her. More merriment ensues when the CIA and the Chinese Communists get involved. Finally the suave Frenchman succeeds. Afterwards he gets in trouble with his wife.
