You don't remember anything. Not even your own name. Opening your eyes, you saw this. Two rows of seats to the right and left. An unfamiliar, snow-covered landscape flashes past the wide oval windows. A train. You get up. There are three other guys lying besides you. Nothing works except the light. But then the guys wake up and ask one question.
What's happening?
They replied that they didn't know how they got here either. The silence was broken only by the sound of wheels on the rails. And nothing else. You and these three guys don't know if anyone else is there. You're locked in with them.
