Attack of the Dead: Osovets is a World War I historical drama set during the brutal 1915 Battle of Osovets. After failed assaults on Russian defensive positions, German forces deploy chemical weapons—cylinders of chlorine gas—in a devastating new offensive. Russian Lieutenant Kotlinsky discovers the attack moments before it begins but lacks time to evacuate his troops. Facing impossible odds and a lethal gas cloud, he rallies his company to mount a desperate final stand. The film chronicles the harrowing clash between soldiers caught in one of history's first large-scale chemical weapon attacks, blending visceral combat with the human cost of industrial warfare.
