The scientist Prof. Dr. Franz Hergarten has to leave his playmate, the blonde Lisa, at home, because he is supposed to bring highly explosive and important documents from Germany to New York as an important secret bearer and courier of a certain organization. An ocean liner is chosen as the means of transportation. German security forces are to accompany him and shield him from unwelcome strangers. Soon Hergarten realizes that some agents of hostile powers, who are also keen on the secret papers, are on him, using every trick and weapon imaginable - including women.
