Travel back in time to a tented field hospital on the coast of France in WWI as a team of doctors, nurses and women volunteers work together to heal the bodies and souls of men wounded in the trenches. The hospital is a frontier: between the battlefield and home front, but also between the old rules, hierarchies and a new way of thinking. Watch all 6 episodes of The Crimson Field this Sunday starting at 4 p.m. | Iowa PBS
