Smog: Thick, deadly smog blankets the globe, reducing visibility to less than a few metres. In a secluded farmhouse, a woman and her overbearing husband attempt to find resources and survive using a series of walking trails crafted from ropes and stakes. One night, the woman is alerted to the presence of someone or something else deep in the smog. Desperate to escape the farmhouse, the woman attempts to meet the unknown and risk everything to leave her loveless and abusive relationship behind.
