Anya Vetrova arrives at "Quiet Pine" — a bright house by the forest where her sister Liza grew up. The shutters are open, the sun is in the windows, and the kettle in the kitchen is still warm.

Only Liza does not come out to meet her. The gates are held by a code lock, and the rooms are silent. Find the fuses, solve the clues, talk to those who live here — and find out where her sister disappeared to.
