It was always a joke. The "what ifs" and the planning were just conversations to have fun with. Who would be the first to go? Where would people be safe? Who would survive the zombie apocalypse? No one is laughing anymore. Awakening to a nightmare, Dan Foster is forced to flee his suburban Chicago home. Together with his wife Abby and little girl Katie, they begin a dangerous trek across the wintery Midwest in hopes to reconnect with his brother in the heartland of Wisconsin. Dan soon discovers the ravenous hordes of undead are not the only things out there that threaten the lives of his family. Can he stay the man he is, or will he need to become something more dangerous in order to protect the ones he loves? In the end, how much of Dan's humanity will survive this dying world?
