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.
