What happens?
A man is chopping wood in front of his cabin in the middle of stinking nowhere in the French countryside with his two teenaged daughters doing other work. A car with a truck behind it approaches in the distance. It is a car full of Nazi SS and the truck has about 15 soldiers. The guy in the car is very nice but eventually cuts to the chase. There is a missing jewish family from way back and he just wants to finish up the paperwork to clean it off his to-do list.
In the end they are shooting through the floorboards at the family hiding below.
Not that we have a problem with our government and Jews, but even back then, they would find and scrutinize you no matter where you lived. Our current government is even more vindictive and has much better technology. If the SHTF and our government is intact, nobody will survive “off the grid”. They will share the suffering any way they can.
