Claiming to be suffering from amnesia, an 18-year-old girl (Gigi Perreau) asks Perry (Raymond Burr) to find out who she is and help restore her memory. As it turns out, the girl has plenty to forget: Her name is Doris Bannister, and she is the daughter of Lisa Bannister (Osa Massen)--who herself is the daughter of the East German Communist party leader, and is living incognito in the U.S. When Stefan Riker (a pre-Hogan's Heroes Werner Klemperer) arrived in America threatening to expose Lisa, Doris pretended to fall in love with him to throw him off the track. Thus, when Riker turns up murdered, Doris is accused of the crime--and Perry really has his work cut out for him!
