An explosion.

You wake up and rush to a window, hearing a loud explosion. You see rows of tanks and soldiers, all bearing a Nazi Swastika on their arms. They're marching towards you.

"Nadiya, get up, Now!" You shake her arms. She yawns and stands up, realising she is naked, she covers herself with her arms.

"What?" She puts on her clothes.

"The SS are here, a lot of them. We have to go, NOW!" You both take as much as you can and run to the nearest Soviet Union remnant outpost. There's nothing else you can do.
