This film begins with a man planting a canister of knockout gas on a passenger airplane in flight and after retrieving some scientific papers from a highly regarded rocket scientist parachuting out just before the aircraft crashes into a nearby mountain. Concerned about the possibility that the scientist's papers may have been compromised the French send "Agent X-77 Serge Vadile" (Gerard Barray) to the crash site to investigate. Surprisingly enough, however, is that the scientist in question just happens to be one of only two survivors of the crash and as a result measures are immediately taken to ensure security in the local hospital at all costs. And this becomes even more important due to the fact that his papers were encoded and only he knows how decipher it. Now rather than reveal any more I will just say that this was a rather routine EuroSpy film which suffered from extremely annoying music between scenes along with poor editing which gave the film a rather choppy feel throughout. On that note, about the only item of interest was the presence of Sylva Koscina (as the nurse named "Mania") who was absolutely breathtaking. Even so, it wasn't enough to overcome the faults just mentioned and for that reason I have rated this film accordingly. Slightly below average.
