Otto (Conrad Veidt) is a respected book seller, and an emigre from the Nazi Germany he despies. However, his twin brother is very much on brand with the regime, indeed he has also come over to the USA but he is setting up a spy ring! He forces Otto to become part of his network but in a struggle Otto is forced to kill his brother.
Otto takes the part of his brother, and now within the spy network begins his plan to bring it down from within. However, he also encounters fellow agent Kaaren (Anne Ayers) who has become disillusioned with the regime...
An enjoyable film with good performances and emotion leading to great sacrifice. The best part of the film though is definitely Veidt who plays twin brothers with dramatically different characters. Unfortunately this was one of his last films before his early untimely death.
