War Nurse (1930)

At the outbreak of the World War, American women from all walks of life join a volunteer nursing outfit in France. Some volunteer out of a sense of duty while others travel to France because that's where all the men are. The nurses are surrounded by death and disease and must sacrifice their own comfort and safety in service of the wounded men who need them. The soldiers, so far from home and facing an uncertain future, are desperate for female companionship, but not necessarily the kind of romance the nurses are hoping for. Pretty young Joy hits it off with Robin, a fellow New Yorker, while no-nonsense Barbara tries to fend off the advances of Wally, a cocksure young flier. Joy's wartime romance takes an unexpected turn, with serious consequences, and Barbara reconsiders her romantic notions when Wally is sent on a dangerous mission.
