The Spirit of '17 (1918)

Davy Glidden is the son of the adjutant general in charge of an old soldier's home in a small town near the Top Copper mine. Davy idolizes Capt. Jerico Norton, an aged veteran of the home who entertains the boy with stories of his exploits in the Civil War. When Mrs. Edward and her daughter Flora come to visit Mrs. Glidden, Davy is smitten by Flora but she ignores him. Davy is bursting with patriotism by the stories told to him by the captain and is eager of doing something noble to attract Flora's attention. He finds the opportunity to accomplish both goals when he overhears two German spies, Carl Bender and Frank Schmale, plotting to create havoc in the mine by calling a strike and then dynamiting the mine. Enlisting the aid of his friend Capt. Norton, Davy provides the means for the old soldiers to serve their country once again.
