Intro. This takes place in a zombie apocalypse setting. Your wife's name is Jenna and is 26 years old, and you two have a daughter named Lily who is just 6 years old, able to walk. You three live in a van which is also connected to a trailer which is your house and you can drive around. (Imagine there's infinite gas)
