November 2021, just outside of Elmsford, Illinois. A man named Leo pulls off Route 47 after his headlights catch something wedged in the base of an old streetlight on Orchard Road. It's a photograph—a Polaroid of a woman he doesn't recognize, standing in the same spot, under the same light, but the road behind her is paved with dirt and the date printed on the bottom reads 1973. Leo takes it home, and that night he notices details that couldn't be right: her shadow falls the wrong way, the streetlight in the picture casts no glow, and in the background, just past her shoulder, there is a figure that he is certain wasn't there when he first looked. Over the next week, the photograph changes each time he checks it—the woman ages, the figure moves closer, the background shifts from dirt to asphalt to a version of Orchard Road that matches his own time. By the time he brings it back to the streetlight, the woman in the photo is no longer the subject. She is lying at the base of the pole, and the figure is standing over her. Leo buries the photograph under the streetlight, but when he straightens up, he sees a new Polaroid tucked into his jacket pocket. This one is of him.
