"Hard Boiled" Haggerty (Milton Sills) is a flight lieutenant who uses German planes for target practice during WWI. For all his bravery in the air, Haggerty is something of a clod on solid ground. Thus, when he gets mixed up with a pair of twin sisters (both played by Molly O'Day), our hero messes up to the point that he faces a court-martial. Only the Armistice saves Haggerty from feeling the full force of Military Justice. Restored to his original rank, our hero is able to escort the twin with whom he's fallen in love back to America. Fans of Milton Sills were satisfied, though some complained that Hard Boiled Haggerty didn't contain enough aerial action to suit them. ~ Hal Erickson, Rovi
