The higher you go, the deadlier it gets. The only habitable place left for humanity is above 8000 feet. Below 8000 feet dwell the monstrous creatures that killed 95% of the human population. A single father (Anthony Mackie) and two women venture in a dangerous journey to face creatures to save the life of a young boy since the city is below 2.400 m height. The fight is just getting started.
