Enemy agents Sava (Edward Mulhare), Karn (Diana Hyland) and Veltran (David Frankham) pool their efforts to kidnap prominent European statesman Anton Dieter (Anton Dieter). Their plan is to exchange Dieter for a Communist agent currently in Federal custody. Inspector Erskine (Efrem Zimbalist Jr.) must locate the kidnappers in order to avert an embarrassing international incident and to plug up a potentially dangerous breach in national security. ~ Hal Erickson, Rovi
