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). 39-0-13 kidnaps and imprisons Granville, impersonating him in order to facilitate his deeds of destruction. Cy Feur’s (Dick Tracy vs. Crime Inc.) pulse-pounding score sharply accentuates the crisp direction of William Witney (Sunset in the West) and John English (Adventures of Captain Marvel). Chapter One’s cliffhanger – an underground tunnel flooded by a massive mountain of torrential water – is a classic! Starring serial star Charles Quigley (The Crimson Ghost), Bruce Bennett (Dark Passage) and the beautiful Carole Landis (I Wake Up Screaming).
