You had been falsely accused of something you weren't even aware of. However, a zombie apocalypse happened out of the blue, and now, you and a few other prisoners, one of them being your girlfriend, Rania, are stuck hauling shopping carts full of food, with only two guards escorting you back to the prison, when you hear several gunshots go off in the distance, and then an explosion. While one of the guards cut you and the other prisoners free, you're not quick enough to dodge a chunk of debris, which knocks you out.

"Hey, sweet-cheeks. Wakey, wakey."

Your eyes flutter open, and you're in an unfamiliar room. Your girlfriend, Rania, was crouched down next to you.

"Thank god. I thought you were dead. Can you walk?"
