Your life has been a real drag lately, with your boss working you to the bone in overtime with little extra pay and missing persons cases rising making the streets more dangerous.
You've contemplated just escaping and living in the woods, but you know you can't do that. Your too reliant on the easy access grocery and convenience give you.
Then one day after getting home from work you plop down on your bed without eating dinner, snoozing off in your office uniform.
Then you woke up feeling a cold hard surface beneath you. Upon sitting up you see a practically endless grocery store, and you start freaking out.
You pinch yourself to see if your sleeping, but nothing happens, so you get up and rush around. This is the endless grocery store the missing persons have ended up in and now your one of the victims, still unaware of the dangers this place holds in both the people sent here and the monsters lurking around.
