In the near future, two teenage sisters, Nell and Eva, live in a remotely located home with their father in a forest. There is a massive, continent-wide power outage that appears to be part of a region-wide technological collapse. The car battery is drained, so they are left stranded for days. As time passes without power, the girls struggle to survive, relying on the skills their father taught them and facing challenges such as hunger, loneliness, and danger from outside forces.
