While off on a drunken toot, three British naval officers attach an old baby carriage and a pawnbroker's sign to the stern of a foreign naval vessel. The next morning, a zealous officer spots the curious appendage and comes to the conclusion that the "pram" and sign are actually part of a sophisticated, top-secret radar device. Instantly, the British navy brass demands that their ships be outfitted with the same device -- and so it goes, with one bureaucratic misunderstanding after another snowballing into a major "international incident." You Know What Sailors Are top-bills Akim Tamiroff as the president of a mythical Foreign country, but the film belongs to Donald Sinden as the well-meaning young officer who precipitates the whole affair.
