Sarah Phelps’ gripping drama tells the story of World War One’s front line medics – their hopes, fears, triumphs and tragedies. The tented field hospital in which they work is a frontier; between the battlefield and home front, but also between the old rules, hierarchies and a new way of thinkingddd
　　Oona Chaplin (The Hour, Quantum Of Solace), Hermione Norris (Spooks, Cold Feet), Suranne Jones (Scott And Bailey, The Secret Of Crickley Hall), Kevin Doyle (Downton Abbey, Scott And Bailey), Kerry Fox (Shallow Grave, An Angel At My Table) and Marianne Oldham (WPC 56) star as the dedicated team of doctors, nurses and women volunteers working together to help the sick and injured.
　　Together they embody an attitude of endurance, supreme courage and hope. Above any enmities or rivalries, they will all come to share a common bond as they experience the horror, the danger, the adrenalin, the joys and, most of all, the death-defying intoxication of simply being alive in the face of mortal danger.
