Every clue, every spiral scar seems to be leading them towards an unpredictable abyss. The secrets hidden behind familiar faces, deliberate traces, and unknown threats make them wander between truth and illusion. What is pursued is not simple crime and punishment, but the cold logic hidden deep in time and human nature. As the mystery gradually emerges, they realize that darkness has never been just on the outside, but lurks deep in everyone's soul. In the end, when the truth was revealed, what greeted them was unexpected sadness and silent despair.
