Abel Gance directs this French drama remake of the 1919 silent film of the same name. Having witnessed first-hand the horror and destruction of the First World War, scientist Jean Diaz (Victor Francen) is determined to never allow the world to be consumed by such chaos again. To this end he develops a device which he is confident will eliminate warfare forever. However, as the governments of the world begin gearing up for yet another all-consuming conflict, Diaz's device is used as just another weapon of war. Furious at the misuse of his machine and the sheer ignorance of those in power, Diaz turns to more unorthodox measures in order to make his point.
