Every soldier knows it: There's nothing more dangerous than a young lieutenant fresh out of the Academy - Blutch and Chesterfield get away from the 22nd Cavalry and go spend some R&R at - Fort Bow, their old posting on the frontier. That's where Chesterfield's flame Amelia lives-the daughter of Colonel Appleton. But when the cavalrymen arrive, they find the young lady dancing with a dashing young lieutenant. When a young Native American boy gets mixed up in it by mistake, it doesn't take long for the situation to spiral out of control.
