Plot.
As described in a film magazine, Helene Palmer (Breamer) is estranged from her husband Orrin (Rawlinson) due to the attentions paid to her by a man about town. After the United States enters World War I, she takes up war work and pleads with men from all walks of life on the steps of the New York City public library to enlist. Her husband joins his company and goes abroad, and she induces her male friend to also join the colors. She then goes to France where she ministers to the sick and destitute. The Germans invade the town and she remains behind with those too ill to be moved. A German officer goes to her room and is about to assault her when the American troops arrive, and she is saved by her husband. There is a reconciliation between them. The film has a prologue where actresses representing Britannia, Italy, and the United States answer the call of Belgium and France, and the film ends with an epilogue with a "league of nations" tableau.
