Lt. Siegfried Sassoon, a poet and war veteran, is facing court-martial for publicly decrying British conduct in World War I. His poet friend Robert Graves pulls strings to get Sassoon placed in a psychiatric war hospital in Scotland, where soldiers are to be swiftly rehabilitated and sent back into battle. There, Sassoon meets a sympathetic doctor and also Wilfred Owen, whom he encourages to pursue poetry as a form of wartime therapy.
