Les vampires (1915)

As a spate of grisly murders and mysterious disappearances terrorise Paris, the inquisitive reporter for The Globe, Philippe Guérande, and his loyal ally, Oscar Mazamette, embark on a peril-laden mission to expose the Vampires: a nefarious, well-connected organisation of arch-criminals preying on the innocent. But in this white-knuckle cat-and-mouse game of death, the dauntless companions are up against formidable adversaries, the Grand Vampires, and the sinister underground society's murderous muse: the gracefully deadly assassin, Irma Vep. In the imminent, once-and-for-all final confrontation with the forces of evil, can valiant Philippe and Mazamette thwart the Vampire menace before more people have to suffer?
