This is one of those sinister mellers, photographed in low light tones, with a generally implausible story populated with spies, secret weapons and nice young couples who get innocently mixed up in espionage. It’s well done, but the maddeningly impossible plot [from an original story by Ben Roberts and Sidney Sheldon] sets it down as routine.
Nancy Kelly and Richard Carlson, as the innocents who get caught in the meshes of the spy ring, both give surprisingly good performances for roles of this type.
Carlson is a young physician into whose car climbs an inventor who has escaped from a sanitorium, where he has been held by the spies.
Robert Siodmak’s direction varies from the slow pace of mystery thrillers to chase sequences, but never achieves full success at either end of the scale. That’s largely due, however, to the unreal story.
