In the near future, in another reality, an abandoned building becomes the silent witness to the extinction of humanity. Through the memories engraved on its walls and echoes, it narrates the tragic story of how humanity succumbed to addiction to a drug that, by eliminating the feeling of loneliness, led to devastating isolation and, finally, to its disappearance. The story is narrated by an artificial intelligence voice to give it coldness and accompanied by a minimalist jazz soundtrack to bring warmth, recorded inside an empty church, resonating with the ghostly beauty of everything that was left behind.
