In order for the American Side to work, even a little bit, it's essential that you know nothing about Tesla, the man who developed alternating current. Because if you know of him, you'd know that he had no such dream of creating the mcguffin that drives the movie. Because the premise is ridiculous, the lengths to which various individuals and groups go to acquire the plans is simply not believable. But this movie has other shortcomings besides. To advance the plot, the protagonist, a down-in-the-mouth gumshoe who drives a Dodge Dart, is given entree to daytime cocktail parties and evening soirees where he is able to chat up the rich who for some reason feed him bits and snatches of what they're up to instead of simply calling the cops and having the guy thrown out. The movie is also replete with coincidences and characters whose function is to provide knowledge so as to advance the mystery, but whose fortuitous appearance stretches credulity. For example, the boat owner who hired our hero early in the film and to whom our hero returns in one of his hours of need just happens to teach physics and knows all about Tesla. There's more, but it's just too silly.
