2018 documentary film directed by Peter Jackson

At the height of the First World War, two young British soldiers must cross enemy territory and deliver a message that will stop a deadly attack on hundreds of soldiers.

Set in an alternate WWI reality where a senseless war rages on, two soldiers on opposite sides of the conflict play a joyful game of chess. A heroic carrier pigeon delivers the soldiers' chess moves over the battlefield as the fighting escalates. Neither soldier knows his opponent as the game and the war builds to its climatic final move. Whoever wins the game, one thing is for certain: there are no winners in war.
