A Lady Without Passport stars Hedy Lamarr in the title role. Lamarr plays Marianne Lorress, a concentration-camp refugee who takes up residence in Cuba while waiting permission to enter the U.S. Immigration agent Pete Karczag (John Hodiak) decides to use Marianne as bait to entrap Palinov (George Macready), the brains of an alien-smuggling ring. Pete eventually falls in love with Marianne, but she despises him for using her--at least until fade-out time. Despite the tattoo on her arm, it is difficult to believe that Hedy Lamarr has survived a Nazi concentration camp; she appears instead to have staged a desperate escape from the MGM makeup department. This aside, A Lady Without Passport is an acceptable (and commendably short) crime meller.
