Postmaster's daughter Sally Haston, living in the Blue Ridge Mountains, loves Steve Carey but wants him to enlist and fight the Germans during World War I. At the training camp, Steve is unhappy and frequently argues with his roughneck tent mate, Billy Murphy. Steve deserts to visit Sally, who quickly accompanies him back to the camp, where Captain Roderick Brooke sympathetically explains the purpose of the war. Later, moonshiner James Grogan holes up with a gun to escape the draft and holds Sally prisoner. Her father organizes a posse, but Steve, on leave, rescues her and then announces that he is leaving for Europe to fight for democracy.
