Into a photography studio full of large fantastic machines steps an elderly couple. The bearded proprietor explains the equipment and gives them a demonstration: he starts machines whirring, and projects a painting of three women onto a large screen; suddenly the women begin to move. The customers are impressed. First the women sits in the special seat: she's projected onto the screen, and her good nature comes out in the laughing image. Then it's the man's turn, but the machine discloses a vastly different nature in him. Will his reaction threaten our proprietor's inventions?
