The Lightning Raider is a 1919 American action film serial directed by George B. Seitz. It was the on-screen debut of Boris Karloff, albeit as an extra. The film serial survives in an incomplete state with some reels preserved at the Library of Congress Public Archives of Canada/Dawson City collection and other film archives, but it is not available on home video. The serial was shown in France as Par Amour.

Plot

A beautiful young woman is in reality a daring master thief. While fleeing the scene of her latest robbery, she meets a handsome young millionaire named Thomas Babbington North. The film belongs to the sensationalistic "Yellow Menace" genre of its time, with Warner Oland playing the insidious Oriental Wu Fang.
