Finding yourself in an unknown place without memories, what will you do? Would you look for clues, trying to find out what's happening here and who you are. Or did you start your life from scratch?
Our hero was lucky enough to be in this situation, but the environment is not the so pleasant: crashed walls and ceiling, which are ready to fall down for one sneeze; old equipment of the communist's times, who have not seen cares for centuries; The piercing cold wind blowing from all the cracks. Icing on the cake is an angry guy with nasty temper and his bloody leg.
The further development of the story depends on you. And remember, the mind forgets everything for a reason!
