In 1915 France, Major Brand commands the 39th Squadron of the Royal Flying Corps. The young airmen go up in bullet-riddled "crates" and the casualty rate is appalling, but Brand can't make the "brass hats" at headquarters see reason. Insubordinate air ace Captain Courtney is another thorn in Brand's side...but finds the smile wiped from his face when he rises to command the squadron himself. Everyone keeps a stiff upper lip.

Major Vickers is an officer at the 27th Lancers in India 1856. When the regiment is on maneuver, the barracks are attacked by Surat Khan and his soldiers who massacre British women and children. This leaves an inextinguishable memory and Vickers promises to revenge the dead.
