It's late summer, 1997, on an old swing bridge over Bayou John in the Louisiana swamp. The bridge tender, an old man named Elias Thibodeaux, has been keeping a lantern lit in the control booth for forty years — not for the boats, but for something that comes at midnight from the water. When a stranded traveler named June arrives after her car breaks down on the bridge, Elias tells her the story of the thing that lives beneath the swing span: a silent figure that waits on the bridge every night, never moving, never speaking, but always watching. June doesn't believe him — until she sees it herself. What follows is a quiet, creeping encounter with something that doesn't belong, a thing that has been waiting for a very long time. Set entirely on one bridge, in one hour, under a bruised sky and a heat that doesn't break.
