Over the years in the movies, microfilm has been pretty much hidden everywhere as a way of hiding it from the enemy, and here, it is in the collar of one of two dangerous black panthers. A bit of documentary narration at the beginning goes into the detail about that nature of the beautiful large cat, and it's not one you want to tangle with, even over its diamond collar that contains valuable secrets. A train accident with the two cats aboard causes them to escape, and good agent Marta Toren joins forces with U.S. agent Howard Duff to find the panthers before the microfilm falls into the hands of enemy agents. This takes them out into the middle of nowhere, on occasion spotting each of the panthers through their binoculars and the telescopic lens of their rifles. But as they aim preparing to fire, something always happens, making it appear that someone among their group doesn't want them to have access to the valuable collar or its even more valuable secrets.
Compact and tense, this cold war spy drama is very well done, the type of crowd pleaser that had post World War II audiences enticed by all the intrigue going on in the world around them. It is never identified what group the enemy agents belong to, but with supporting actors like Walter Slezak, Philip Dorn and Kurt Krueger, the audience is kept guessing which ones are the good guys and which ones are the bad guys. One of the great scenes occurs when Toren and Duff track the collared panther to a cabin in the middle of nowhere and Toren endeavors to lock the panther in so it won't escape. There seems to be a cut scene though, because when we next see the panther, it is already in a cage as everybody surrounding it wonders how they are going to get the darned collar off. That's a minor mishap, however, because the rest of the film is exciting and filled with tension.
