This World Alone (2018)

This World Alone is an independent feature film about three women living in seclusion following a cataclysmic event that left the Earth without technology or power. Sam (Belle Adams), a book-obsessed girl in her late teens, is raised by her strict, "only the strong survive" mother, Connie (Carrie Walrond Hood), and their optimistic, earthy friend Willow (Sophie Edwards). After Willow suffers a life-threatening injury, it's up to Sam to head out of her protective home for the first time and journey to a settlement a few days away to collect medical supplies. Along the way she meets Dart (Lau'rie Roach), a weak young man out on a "walkabout" attempting to prove himself to his community. The two of them come of age together as they face the physical and emotional challenges of a world reclaimed by nature.
