Brahms Baby Food has signed a contract to supply powdered milk to the government and all employees must undergo a security clearance check. On the home front Greta is informed the landlord wants her apartment for his newly-married niece. The ISA men visit Peter's apartment and then interview the man-in-the-middle and Greta in her apartment. Peter and Greta convince the landlord that it would cost him too much to fix the apartment up for his niece and he agrees that Greta can continue living there. The ISA men return and say they suspected Greta was posing as Peter's wife but after talking to many witnesses realize it's a very modern marriage and that the apartment upstairs is her art studio. Having passed the security clearance Peter and Greta celebrate. Peter finds out the next day Brahms has signed a business deal with West Germany and informs Peter the German security checks are very thorough.
