The Master Mystery(1918)

In this action-packed serial, government agent Quentin Locke infiltrates a corrupt patents company, only to run into the gleaming terror of its robot protector, the Automaton. In order to save the beautiful Eva Brent and find a cure for the dreaded Madagascar Madness, Locke suffers an inhuman array of tortures and physical restraints. He is chained, tied with barbed wire, padlocked in a crate and thrown in the water, tied beneath a descending elevator, strapped to an electric chair, and bound in an elaborate Oriental torture chamber.
