The play Journey's End takes place over four days in a dugout on the Western Front during World War I. The confined setting creates a sense of claustrophobia and doom. While the play does not follow a traditional narrative structure, Sherriff uses complications and shifts in mood from calm to tension to take the audience on an emotional journey. Each character plays a role in this, from the light relief of Mason to the friendliness of Osborne. Though criticized for its lack of structure, Sherriff's realistic portrayal of war through the characters' varying speech and emotional responses allowed the audience to draw their own conclusions about the human experience of war.
