When a virus outbreak hits, college student Bailey is scratched and bitten by the infected but never turns. She flees with her friend Zoe, Ethan and his sister, Darren, and gun shop owner John and his son, heading for a cabin in the woods. Thrown from a car, Bailey discovers the infected treat her as one of their own and don't attack—she walks through the horde and reunites with her companions at a mall.
