A very British parody of the 1920s private eye 'Bulldog Crummond'. After the dastardly Count Otto Von Bruno (Richard E House) and his accomplice kidnap a professor with the ability to produce synthetic diamonds, it is up the professor's daughter, Rosemary (Diz White) to call for help. Who better call upon than the dashing Captain Hugh 'Bullshot' Crummond (Alan Shearman), an ace WWI fighter pilot.
