The Disturbed Sentry(1912)

Four soldiers are passing away time when one, looking through the window, spies a pretty girl sitting on a veranda on the opposite side of the street. Naturally, the cards are left, and the four are soon crowding the window, each vying for the girl's attention, much to her amusement. Even their officer, who enters the room to scold them, is soon absorbed in making eyes at the charming creature. When the colonel surprises them and looks through the window, he's disgusted by the sight that meets his eyes. (stumfilm.dk)
