Newly Mastered in HD from a 4K scan! Considered by most to be one of the best, if not the best serials of all time. Three circus stuntmen track down a ruthless madman known as 39-0-13 (Charles Middleton, Emperor Ming of Flash Gordon Conquers the Universe), bent on destroying the wealth and integrity of his former employer, multi-millionaire Horace Granville (Miles Mander, Murder, My Sweet).
