THE SPIDER'S WEB (1938)--a colorized 15-chapter serial in one video

A crime fighter known as The Spider battles a villain called The Octopus, who is out to sabotage America and install his own government. The masked crime lord, is bent on crippling America with a wave of terror. He demands tribute from railroad magnates and other captains of industry. Richard Wentworth, an amateur criminologist who is friendly with the police and is secretly "The Spider," a masked vigilante, is equally determined to destroy the Octopus and his gang. Pleasant and smiling in civilian life, Wentworth is frequently ruthless as The Spider, using his two .45 semi-automatic pistols against any public enemies who attack him. The Spider uses a knotted rope to swing about.
Wentworth also masquerades as affable underworld lowlife Blinky McQuade. Disguised as McQuade, Wentworth can infiltrate gangland as a hired gun or getaway-car driver and keep current on the mob's illegal activities.
The only people who know Wentworth's various identities are his assistants Jackson and Ram Singh, his butler Jenkins, and his fiancée Nita.
The Octopus was a pulp villain written by Norvell Page, who also wrote most of The Spider pulp novels. He is garbed completely in white and is only ever seen by his henchmen while sitting in his throne-like chair. Unlike the pulps, where The Spider is dressed in an all black cape, mask, suit, and wide-brimmed fedora, in the serial he is garbed in a black suit and fedora, but with white web-like markings on his lightweight cape and full face mask. The serial follows the standard formula of fights, shoot-outs, Wentworth's friends being kidnapped at various times and needing to be rescued. Each chapter ends with The Spider or his friends in deep trouble, often about to be killed, but the effect is spoiled by a trailer for the next episode which follows, showing them rescued and continuing to fight the villains. The secret headquarters of The Octopus is found by The Spider in the final chapter; he has unwittingly given himself away to Wentworth and realizing this, Wentworth must now die; but as The Spider, Wentworth is triumphant in the end, unmasking The Octopus and ending his national reign of terror.
During the serial The Spider uses his web line a number of times to get out of trouble. Commissioner Kirk (changed from Kirkpatrick in the pulps) suspects that Wentworth is The Spider during one chapter. The Octopus' gang, like their boss, wear robes when they gather together in his presence. The Octopus ruthlessly executes all who failed him; in case of trouble, The Octopus always uses a false arm and hand, which allowed him to conceal a pistol in his real hand hidden beneath his robes.
