This is a most conventional propaganda picture for the glory of the FBI with careful documentation of how expertly they handle their duties and get their commie villains. It is very similar in character to Henry Hathaway's "House on the 92nd Street", which though is a so much more interesting film for its characters, especially Signe Hssso. Here there are no characters except stereotypes.. The one character for which the film is worth seeing is Finlay Currie as the Russian scientist who gets into trouble, and his way of handling his very tricky path out of an immense abyss of trouble. It's not a bad film, but it is supremely superficial, varnished to 101% artificial perfection, but for Finlay Currie. who makes a great performance.
