In Storm Warning, Ginger Rogers stars as a schoolteacher visiting relatives in an unnamed small town. She happens to witness the beating death of a man at the hands of the KKK. Rogers soon discovers that the whole town is controlled by this vigilante group, and that her loutish brother-in-law Steve Cochran is one of the group's members. D.A. Ronald W. Reagan is the man who breaks the stranglehold of the hooded terrorists--through the simple expedient of walking into one of their meetings and calmly identifying each of them by name.
