During the Nazi occupation of Belgium during World War II, a Belgian resistance group revives the newspaper "La Libre Belgique" to expose and counter Nazi propaganda efforts to deceive the people. They are so effective that the Nazis offer a reward for the capture of the paper's staff, although they don't know their identities. One of them is a well-known entertainer, and when his jealous partner hears of the reward, he turns him in. The paper's publishers escape capture, but their staff doesn't. The paper's founders must find not only a way to keep from getting captured by the Nazis but keep their newspaper going and get their staff released.
