Ally Lane survived the explosion of the Betty Loo only to find herself turned over to the man responsible for the death of her friends. She fights her way free and teams up with a man from a past she'd rather forget. Betrayed by all those she comes into contact with, she trusts no one. She travels across the country with a team of mercenaries fighting off zombies to protect the one man who might be able to save them. The man who wants to be the next president.
