Synopsis

At the height of the First World War, two young British soldiers, Lance Corporal Schofield (George MacKay) and Lance Corporal Blake (Dean-Charles Chapman), are stuck with 1,600 other British soldiers in the trenches of the Hindenburg Line on April 6, 1917. Their superior, General Erinmore (Colin Firth), assigns them a challenging and dangerous task to personally deliver a letter to Colonel Mackenzie (Benedict Cumberbatch), commander of the 2nd battalion.

In a race against time, they must cross enemy territory and deliver a message that could potentially stop a deadly attack on hundreds of soldiers, one of them being Blake’s own brother.
