In other words,this film is a surreal ride.

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

Story: It's very simple but honestly that is fine.

The movie is surprisingly subdued in its pacing, its characterizations, and its go-for-broke sensibilities.

If you want drama, suspense and mystery, YOU got it all here. Van Heflin provides a riveting seeker of truth here in this 1967 movie. He is also naive, when it comes to his trade. But he quickly learns how to play the game of spy. When you watch it, you think it was made in the 70's. This movie introduced Heidelinde Weis (to the English-speaking world). She is a great side-kick, and (i guess) romantic partner (?).Buy and watch this well-made movie.
