A global pandemic is spread across the world causing people to hunt their own. Everyone has the virus in them but the only way it activates in your body is when your heart completely stops. On everybody's last day of schooling they have to take a test to determine their rank in the society. The two best friends Elliot and Tyler go on a mission with the flights. Elliot somehow pulls Tyler away from the group and then they get lost and they have to scavenge the abandoned cities and towns for shelter, food, drinkable water, and anything to help with surviving.
