One hundred and fifty miles away, Jack and Lucy’s father is unaware that his children are still alive. He is struggling with a new normal, and desperate to escape his own city. David has also taken on the role of protector for Tasha, the orphaned daughter of a housemaid, while they fight for their own survival. Come along as some escape from the radiation and fires, some run from the gangs of freakers and all run from the enemy that has invaded America.
