Sam Mendes, the Oscar®-winning director of Skyfall, Spectre and American Beauty, brings his singular vision to this World War I epic. At the height of the First World War, two young British soldiers, Schofield (Captain Fantastic's George MacKay) and Blake (Game of Thrones' Dean-Charles Chapman) are given a seemingly impossible mission. In a race against time, they must cross enemy territory and deliver a message that will stop a deadly attack on hundreds of soldiers-Blake's own brother among them.
