It's an interesting film technically, but the story and characters are very insignificant. An invaluable painting is stolen and collected from a skyscraper roof by a helicopter, and all the rest of the film is the trouble of the police to trace this helicopter and the painting. The motive is obvious, someone needed money, and used the painting for blackmail. We learn about the crook at a rather early stage, and there is no doubt about it when he pushes someone off that same roof of the theft. It's a very ordinary plot of hide and seek, but the end chase is very exciting for its very unusual procedure, and you can follow the entire manhunt from the air. The criminal has no chance of course, his end is inevitable, and the romance of the film does not succeed in making it more interesting. The film is actually only interesting from a technical point of view.
