D.W. Griffith Shorts - An Unseen Enemy 1912
Two girls and their brother live at the little homestead left them by their late father. The brother, having disposed of a portion of the small estate, comes home with the money to show it to his sisters, telling them that they may now enjoy a few of the luxuries of life. As it would be after banking hours before he could get to the village, he places the money in the safe and returns to his office, some distance away. He has hardly departed when the maid, a slattern individual, who has seen him put the money in the safe, attempts to get it. Failing to work the combination, she calls up an erstwhile friend requesting him to come and help her. While these two work, the sisters are locked in the sitting-room, terrorized in a most unique way. The brother, however, arrives after a series of tantalizing delays and apprehends the criminals just as their scheme seems to have succeeded.
