This parody of low-budget 30s detective movies typifies British heroism at its dumbest. Teutonic villain Otto Von Brunno and his evil mistress Lenya crash their plane in the English countryside and kidnap Professor Fenton, who has discovered a formula for making synthetic diamonds. Bullshot Crummond is called to the rescue by the professor’s daughter Rosemary. The two work together to try defeat the dastardly Otto and save the professor in this car-chase and sword-fighting filled adventure.
