Charles Stuart Blackton

A young Englishman falls in love with the children's governess in his step-sister's home. His step-sister, however, cannot abide the class differential in the romance and sabotages it. The young man, in a state of boredom and depression, begins to invite into the house anyone who happens to pass by in the street.

Three-year-old Charles Stuart Wyngate longs to be a Boy Scout, while his seven-year-old sister Violet, who wishes that she was a boy named Bill, desires to help the war effort through Red Cross work. The children play happily after their mother sends for a scout uniform, until they meet another child, Harold, whose father is a pacifist. After Charles punches Harold in the nose, Harold's father comes and explains his beliefs. Mrs. Wyngate tries to convert him by telling of her husband's death in battle in France.

Helene Palmer and her husband Orrin have grown apart, and she becomes infatuated with bachelor Edward Wadsworth. With the outbreak of World War I, Orrin and Edward enlist, while Helene works as a Red Cross nurse in a small French town. Edward is wounded on a dangerous scouting mission near the town and Orrin carries him to safety. The enemy invades during the night, and Orrin rescues Helene as she is about to be overpowered by a German officer. The dying Edward, morally strengthened by his experience as a soldier, encourages the couple to reunite. Soon after, peace is declared.
