The Great War rages across Europe, and not even the serene Yorkshire countryside is free from its effects. The men and women of Downton are doing their part: heir Matthew Crawley and footman Thomas Barrow are off fighting, while Lady Grantham and Isobel Crawley are squabbling over whether Downton should be used as a hospital. Lady Mary is seeing a wealthy newspaper magnate while Lady Edith becomes much warmer and Lady Sybil seeks to ingratiate herself with the staff. Below stairs, as his former wife bedevils John and Anna, Mr. Carson and Mrs. Hughes struggle to keep the house running smoothly.
