In 1917, silent film director Louis Feuillade and writer Arthur Bernède created the character of a mysterious avenger, wearing a slouch hat and a dark cloak -- Judex! His name means "Judge," and he has sworn to mercilessly punish criminals!

Judex appears and disappears like a living shadow. Trained by the vindictive Woman in Black, he is a master of disguise and an excellent fighter. His loyal followers include a female athlete, a reformed ex-convict and a pack of vicious bloodhounds. Beneath the ruins of a castle is his secret lair, where he interrogates his prisoners through a "television" screen.
