The BBC has unveiled a new trailer for Sarah Phelps new upcoming Great War drama, The Crimson Field (formerly The Ark) .

The six-part series tells the story of a tented field hospital on the coast of France, where a team of doctors, nurses and women volunteers work.

The hospital is a frontier: between the battlefield and home front, but also between the old rules, hierarchies, class distinctions and a new way of thinking.

The all-star cast includes: Suranne Jones, Oona Chaplin, Hermione Norris, Alice St. Clair, Marianne Oldham, Kerry Fox, Kevin Doyle, Jack Gordon, Alex Wyndham, Richard Rankin, and Jeremy Swift.

The Crimson Field is currently scheduled to air sometime in the week of 5 – 11th April.
