Frank (Humphrey Bogart), a factory worker, is passed over on a promotion that goes to a Polish man. In anger, he joins the Black Legion (basically the Ku Klux Klan) to punish all foreigners for taking jobs from "true Americans". The story has been done since, but this one is well-made, quick (82 min.), well-acted (Bogart is great and looks so young!) and still powerful. The film isn't perfect (I could have lived without the closing sermon) but still worth seeing. It's also real sad to realize that a film over 60 years old about racism is still relevant.
