Sorry but after 30 years as a real Treasury Special Agent the idea that any country would let that quantity of drugs leave their jurisdiction is a pipe dream (pun intended). This film contained as much stock footage and lines on maps as there was actual acting. Columbia Pictures did a better job with the 1950 film Customs Agent starring William Eythe, Marjorie Reynolds and Jim Backus. The best of the lot was the 1949 film Port of New York with Yul Brenner in his first role. Skip this one until you see the other two.
