The film takes place following a severe drop in the global population. The Survivalist is first seen burying the body of a naked man, and then resetting a bear trap. He is then shown to be living efficiently in the wild in a small cabin; he harvests vegetable crops for food, forages berries, washes clothes in a nearby stream, fertilises seeds with his seminal fluid, and lays traps against intruders around his small farm's perimeter.
