If you inexplicably find yourself in a hut hidden in the forest, you realize that something has gone wrong. The surrounding terrain appears alien. Note with incomprehensible instructions are scattered everywhere. In the hut itself is a strange car. And the most annoying thing is that you can't find a way out of this place. A few days pass and you realize that you've had nothing to drink, or eat, and you do not need to sleep. But now your condition somehow depends on how well the machine works in the hut. Somehow invisible bonds chained you to her. Carefully reading the notes around, and you'll understand that the car requires blood. But where to get it?
