There are maniacs and murder, who have no choice, because they are sentenced to life imprisonment. And now their gray routine decided to diversify the unexpected test. The guests were certainly greeted by choosing the best rooms. But when the cooks were preparing dinner, there was a huge load on the wires, and with the closure knocked out all the electricity.

And the fate of all those present in the colony now lies only in the hands of the most cruel murderers.
