Is every man killed in combat reborn in the sky in the form of a star? Is seeing a bus in your dreams really a sign of impending death? In 1917, Jan Van Meer, an operative with the Allies intelligence services and a renowned expert on folklore, travels across Europe in search of an engineer named Hellequin, inventor of the dream cannon and barbed plant-wire now obsessed with reading the ruins of war. Van Meers mission: not to find Hellequin at all costs. With his trademark wit, original drawing style, and wild animation, David B. takes viewers deep into the torment of the Great War, where beliefs and superstitions inextricably mix with the horror of reality.
