Two young British soldiers during the First World War are given an impossible mission: deliver a message deep in enemy territory that will stop 1,600 men, and one of the soldiers' brothers, from walking straight into a deadly trap.
With brilliant, claustrophobically effective directing choices by Sam Mendes and strong, raw performances from young leads Dean-Charles Chapman and George MacKay, this heart-stopping World War I drama is a unique viewing experience you won't soon shake off. - Four stars
