A voice in the dark. In a surreal and disquieting stage, a man who is immersed in the deepest of darkness in his bedroom suddenly hears a voice that is impalpable like a dream, persuasive and cryptic. An undefinable, mysterious presence that slowly unveils as it leads a dreamlike dialogue between two people which, in the deceitful meanders of flattery, could hide all sorts of surprises. To flee, to leave the room, to turn on a light that might reveal the face, the sense behind that hypnotic voice which seems to envelop him more and more in a clinging, paralysing web. A trap with no exit in which, swallowed up by the darkness, time confounds night and day. In the anguish of the imponderable sequence of deceitful sensations, the gripping epilogue approaches until it coagulates into a chilling grip that only the unknown can provide.
