In 2003 a fungus infects a large proportion of the world's population, turning them into zombies. Fast forward to 2023 and the world is in ruins. Survivors cluster together in quarantine centres, which are as much a prison run by the fascist government as a safe haven from the infected. People survive any way they know how. Living in Boston is one such survivor, Joel Miller. He helps out the resistance, the Fireflies, whenever there's something in for him. The leader of the local Fireflies offers him an opportunity to find his brother in Wyoming if he helps a teenaged girl, Ellie, get to a Firefly group outside the city. She may hold the key to ending the pandemic.
