When a kindly junk dealer gives a group of poor French children a headless toy horse, the kids dub themselves "The Knights Of The Headless Horse." The broken toy becomes their only source of fun as they race down the narrow streets of their village. But suddenly the horse becomes the pawn in another game -- a deadly race against time between a ruthless gang of train robbers (led by Herbert Lom) and the town's honest police inspector (Jean-Pierre Aumont). The stakes are high: A hundred million francs ... and the lives of five innocent children!
